Effect of individual or combined ablation of the nuclear groups of the lamina terminalis on water drinking in sheep. (1/308)

The subfornical organ (SFO), organum vasculosum of the lamina terminalis (OVLT), and median preoptic nucleus (MnPO) were ablated either individually or in various combinations, and the effects on drinking induced by either intravenous infusion of hypertonic 4 M NaCl (1.3 ml/min for 30 min) or water deprivation for 48 h were studied. Ablation of either the OVLT or SFO alone did not affect drinking in response to intravenous 4 M NaCl, although combined ablation of these two circumventricular organs substantially reduced but did not abolish such drinking. Ablation of the MnPO or MnPO and SFO together also substantially reduced, but did not abolish, drinking in response to intravenous hypertonic NaCl. Only near-total destruction of the lamina terminalis (OVLT, MnPO, and part or all of the SFO) abolished acute osmotically induced drinking. The large lesions also reduced drinking after water deprivation, whereas none of the other lesions significantly affected such drinking. None of these lesions altered feeding. The results show that all parts of the lamina terminalis play a role in the drinking induced by acute increases in plasma tonicity. The lamina terminalis appears to play a less crucial role in the drinking response after water deprivation than for the drinking response to acute intravenous infusion of hypertonic saline.  (+info)

A rapid feedback signal is not always necessary for termination of a drinking bout. (2/308)

When a pig is deprived of drinking water, a deficit of body water develops that is corrected when the pig drinks to satiation. If food is available during the deprivation, the stimulus to drinking is plasma hyperosmolality. Because of the delay in correction of plasma hyperosmolality as ingested water is slowly absorbed, it has been thought that a rapid inhibitory signal from the digestive tract is necessary to prevent overdrinking. This concept was tested by measuring changes in plasma osmolality before and during drinking after such deprivation and also after infusion of hypertonic saline. As drinking began, there was a rapid fall of plasma osmolality to levels insufficient to drive drinking by the time drinking ended. This fall of plasma hyperosmolality to subthreshold levels while the pig is drinking seems to make a rapid inhibitory control signal from the digestive tract unnecessary to terminate the drinking bout under these conditions.  (+info)

Thermal dehydration-induced thirst in spontaneously hypertensive rats. (3/308)

Spontaneously hypertensive (SH) rats and normotensive Wistar-Kyoto (WKY) rats were exposed to either 25 or 37.5 degrees C for 3.5 h, and their thermal and water balance responses were compared. After exposure, either a blood sample was obtained or the rats were allowed to rehydrate for 4 h. SH rats had both higher core temperatures and evaporative water losses during heat exposure. Measurements of hematocrit, hemoglobin concentration, plasma protein and sodium concentrations, and plasma osmolality indirectly showed that the SH rats were dehydrated relative to the WKY rats after exposure to either 25 or 37.5 degrees C. SH rats drank significantly more water but also had significantly higher urine volumes than the WKY rats and thus rehydrated only slightly better than the WKY rats. SH and WKY rats had similar levels of water intake and urine output after 24 h of water deprivation. The elevated thermal response of SH rats to heat exposure does not appear to lead to uncompensatable changes in body water status.  (+info)

Osmolality: a physiological long-term regulator of lumbar sympathetic nerve activity and arterial pressure. (4/308)

Acute infusion of hypertonic fluid increases mean arterial pressure (MAP) in part by elevating nonrenal sympathetic activity. However, it is not known whether chronic, physiological increases in osmolality also increase sympathetic activity. To test this hypothesis, MAP, heart rate (HR), and lumbar sympathetic nerve activity (LSNA) were measured in conscious, 48-h water-deprived rats (WD) during a progressive reduction in osmolality produced by a 2-h systemic infusion (0.12 ml/min) of 5% dextrose in water (5DW). Water deprivation significantly increased osmolality (308 +/- 2 vs. 290 +/- 2 mosmol/kgH2O, P < 0.001), HR (453 +/- 7 vs. 421 +/- 10 beats/min, P < 0.05), and LSNA (63.5 +/- 1.8 vs. 51.9 +/- 3.8% baroreflex maximum, P < 0.01). Two hours of 5DW infusion reduced osmolality (-15 +/- 5 mosmol/kgH2O), LSNA (-23 +/- 3% baseline), and MAP (-10 +/- 1 mmHg). To evaluate the role of vasopressin in these changes, rats were pretreated with a V1-vasopressin receptor antagonist. The antagonist lowered MAP (-5 +/- 1 mmHg) and elevated HR (32 +/- 7 beats/min) and LSNA (11 +/- 3% baseline) in WD (P < 0. 05), but not in water-replete, rats. 5DW infusion had a similar cumulative effect on all variables in V1-blocked WD rats, but had no effect in water-replete rats. Infusion of the same volume of normal saline in WD rats did not change osmolality, LSNA or MAP. Together these data indicate that, in dehydrated rats, vasopressin supports MAP and suppresses LSNA and HR and that physiological changes in osmolality directly influence sympathetic activity and blood pressure independently of changes in vasopressin and blood volume.  (+info)

Effect of dorsomedial hypothalamic nuclei knife cuts on ingestive behavior. (5/308)

Previous findings show that rats with electrolytic or excitotoxic lesions in the dorsomedial hypothalamic nucleus (DMN) are hypophagic and hypodipsic and have reduced ponderal and linear growth but normal body composition. DMN-lesioned (DMNL) rats also show altered ingestive responses to naloxone. The present study investigated the intrahypothalamic nerve pathways involved in these DMNL effects and the response of the pathways to deprivation challenges by placing knife cuts posterior (Post), lateral (Lat), ventral (Vent), dorsal, or anterior to the DMN or by administering sham operations. One major finding was that rats with Post or Vent were hypophagic (P < 0. 05) and had reduced body weight but responded normally to deprivation challenges. Post and Lat groups were hypodipsic (P < 0. 05), but plasma Na+, K+, and osmolality and 24-h post-water-deprivation drinking responses were similar in all groups. Naloxone did not suppress the intake of Post rats. It appears that the hypophagia and the reduced body weight after DMNL involve fibers entering or leaving the DMN from ventral and posterior directions, and they may be part of an opioid feeding system.  (+info)

An enhanced effect of arginine vasopressin in bradykinin B2 receptor null mutant mice. (6/308)

Under water restriction, arginine vasopressin (AVP) is released and promotes water reabsorption in the distal nephron, mainly through AVP V2-receptors. It has been proposed that renal kinins counteract the hydro-osmotic effect of AVP. We hypothesized that kinins acting through B2 receptors antagonize the urinary concentrating effect of AVP. To test this, bradykinin B2 receptor knockout mice (B2-KO) and 129/SvEv mice (controls) were placed in metabolic cages and urine collected for 24 hours (water ad libitum). After that, urine was again collected from the same mice during 24 hours of water restriction. Urinary volume (UV), urinary osmolarity (UOsm), and urinary Na+ (UNaV) and K+ (UKV) excretion were determined. On water restriction, UV in controls decreased by approximately 25%, whereas in B2-KO mice there was almost a 60% drop in urinary output (P=0.001 versus controls). In the controls, water restriction increased UOsm by 347 mOsm/kg H2O, approximately 14% above baseline (NS), whereas in knockout mice the increase was 3 times that seen in the controls: >1000 mOsm/kg H2O (P=0.001 versus controls). Compared with normohydration, UNaV and UKV in the water-restricted state increased more in controls than in B2-KO mice. This difference in electrolyte excretion could be explained by greater dehydration in the controls (dehydration natriuresis). In a second protocol, we tried to mimic the effect of endogenous AVP by exogenous administration of an AVP V2-receptor agonist, desmopressin (DDAVP). To suppress endogenous AVP levels before DDAVP administration, mice were volume-overloaded with dextrose and alcohol. UOsm was 685+/-125 and 561+/-58 mOsm/kg H2O in water-loaded controls and B2-KO mice, respectively. After DDAVP was injected subcutaneously at a dose of 1 microgram/kg, UOsm increased to 1175+/-86 mOsm/kg H2O (Delta+490 mOsm) in the controls and 2347+/-518 mOsm/kg H2O (Delta+1786 mOsm) in B2-KO mice (P<0.05 versus controls). We concluded that water restriction or exogenous administration of an AVP V2-receptor agonist has a greater urinary concentrating effect in B2-KO mice than in controls, suggesting that endogenous kinins acting through B2 receptors oppose the antidiuretic effect of AVP in vivo.  (+info)

Urinary excretion of aquaporin-2 in rat is mediated by a vasopressin-dependent apical pathway. (7/308)

Clinical studies have shown that aquaporin-2 (AQP2), the vasopressin-regulated water channel, is excreted in the urine, and that the excretion increases in response to vasopressin. However, the cellular mechanisms involved in AQP2 excretion are unknown, and it is unknown whether the excretion correlates with AQP2 levels in kidney or levels in the apical plasma membrane. The present study was undertaken to clarify these issues. Immunoblotting of rat urine samples revealed significant excretion of AQP2, whereas AQP3, being a basolateral aquaporin in the same cells, was undetectable. Thus, there was a nonproportional excretion of AQP2 and AQP3 (compared with kidney levels), indicating that AQP2 is excreted predominantly via a selective apical pathway and not by whole cell shedding. Urinary AQP2 was associated with small vesicles, membrane fragments, and multivesicular bodies as determined by immunoelectron microscopy and negative staining techniques. In rats with normal water supply, daily urinary excretion of AQP2 was 3.9+/-0.9% (n = 6) of total kidney expression. Treatment with desmopressin acetate subcutaneously caused a fourfold increase in urinary excretion of AQP2 during 8 h. Forty-eight hours of thirsting, known to increase endogenous vasopressin secretion, resulted in a three-fold increase in kidney AQP2 levels but urinary excretion increased ninefold to 15+/-3% (n = 6) of AQP2 in kidney of thirsted rats. Moreover, rats that were thirsted for 48 h and subsequently allowed free access to water for 24 h produced a decrease in urinary AQP2 excretion to 38+/-15% (n = 6) of that during thirsting. In Brattleboro rats or lithium-treated normal rats completely lacking vasopressin action, and hence having extremely low levels of AQP2 in the apical plasma membrane, AQP2 was undetectable in urine. Thus, conditions with known altered vasopressin levels and altered levels of AQP2 in the apical plasma membrane were associated with corresponding major changes in AQP2 urine excretion. In contrast, in such conditions, kidney AQP2 levels and urinary AQP2 excretion did not show a proportional relationship.  (+info)

Effects of water deprivation on atrial natriuretic peptide secretion and density of binding sites in adrenal glands and kidneys of maternal and fetal rats in late gestation. (8/308)

The effects of water deprivation for 3 days were studied in pregnant rats and their fetuses on day 21 of gestation. Maternal water deprivation induced a significant decrease of the body weight in both maternal and fetal rats. This weight loss was accompanied by significant increases in plasma osmolality and haematocrit in both maternal and fetal rats. Similarly, dehydration significantly decreased plasma atrial natriuretic peptide (ANP) concentrations and increased plasma aldosterone concentrations in maternal and fetal rats. Water-deprived maternal rats presented a significant increase in total ANP receptor density in isolated renal glomeruli and adrenal zona glomerulosa membranes. This increase was due to a significant increase in ANPc receptor density in both renal glomeruli and adrenal zona glomerulosa. The densities of total ANP, ANPb and ANPc receptors in fetal kidneys and adrenal glands were not affected by maternal dehydration. These results suggest that the dehydrated maternal rat is able to up-regulate the number of its ANP receptors in its kidneys and adrenal glands, in response to a decrease in plasma ANP concentrations. In contrast, the fetal rat does not seem to be able to regulate its own ANP receptors in response to maternal dehydration, in spite of a decrease in plasma ANP concentrations.  (+info)

Definition of water deprivation in the Financial Dictionary - by Free online English dictionary and encyclopedia. What is water deprivation? Meaning of water deprivation as a finance term. What does water deprivation mean in finance?
Given that water withdrawal is one of the major stressors for animals during long-distance transports, it was the aim to study the effects of prolonged water deprivation on different blood and behavioural parameters of goats and sheep under stable conditions. Withdrawal periods corresponded to EU transport regulations, which allow sheep and goats to be transported for a maximum period of 14 hours, followed by a rest period of at least one hour sufficient for them to drink water, if a further 14-h travel is necessary. In the present study tools for authorities to approve the offer of water were evaluated. Fifteen Boer goats and 15 Blackhead mutton sheep were assigned in a 3 x 3 Latin square design to 1 of the following treatments: AL (ad libitum), SHORT (14 h withdrawal - 1 h access - 14 h withdrawal) or LONG (29 h withdrawal). The study was conducted under stable conditions without transporting the animals. Haematological parameters were analysed at 0, 14, 15, and 29 h. Standing, lying, and ...
TY - JOUR. T1 - Differential regulation of TRPC4 in the vasopressin magnocellular system by water deprivation and hepatic cirrhosis in the rat. AU - Nedungadi, T. Prashant. AU - Cunningham, J. Thomas. PY - 2014/3/1. Y1 - 2014/3/1. N2 - Transient receptor potential canonical subtype 4 (TRPC4) is expressed in the magnocellular paraventricular nucleus (PVN) and supraoptic nucleus (SON) of the hypothalamus. In this study, the regulation of TRPC4 expression was investigated in water deprivation and hepatic cirrhosis. We used laser capture microdissection technique for precise dissection of pure AVP cell population in the PVN and SON followed by quantitative real-time RT-PCR, and immunodetection techniques by Western blot analysis and immunofluorescence. Bile duct ligation elevated TRPC4 transcripts in the SON but not PVN with correlated changes in the protein expression in these regions, as well as increased colocalization with AVP in the SON, with no changes in the PVN. Water deprivation resulted in ...

Sheep and cattle are frequently subjected to feed and water deprivation (FWD) for about 12 h before, and then during, transport to reduce digesta load in the gastrointestinal tract. This FWD is marked by weight loss as urine and faeces mainly in the first 24 h but continuing at a reduced rate subsequently. The weight of rumen contents falls although water loss is to some extent masked by saliva inflow. FWD is associated with some stress, particularly when transportation is added. This is indicated by increased levels of plasma cortisol that may be partly responsible for an observed increase in the output of water and N in urine and faeces. Loss of body water induces dehydration that may induce feelings of thirst by effects on the hypothalamus structures through the renin-angiotensin-aldosterone system. There are suggestions that elevated cortisol levels depress angiotensin activity and prevent sensations of thirst in dehydrated animals, but further research in this area is needed. Dehydration ...
BACKGROUND: Renal endothelial cells from glomerular, cortical, and medullary kidney compartments are exposed to different microenvironmental conditions and support specific kidney processes. However, the heterogeneous phenotypes of these cells remain incompletely inventoried. Osmotic homeostasis is vitally important for regulating cell volume and function, and in mammals, osmotic equilibrium is regulated through the countercurrent system in the renal medulla, where water exchange through endothelium occurs against an osmotic pressure gradient. Dehydration exposes medullary renal endothelial cells to extreme hyperosmolarity, and how these cells adapt to and survive in this hypertonic milieu is unknown.. METHODS: We inventoried renal endothelial cell heterogeneity by single-cell RNA sequencing ,40,000 mouse renal endothelial cells, and studied transcriptome changes during osmotic adaptation upon water deprivation. We validated our findings by immunostaining and functionally by targeting oxidative ...
The rapid decreases in plasma VP and corticosterone that occur after dehydration-induced drinking have been well documented (19, 21, 26, 35, 49, 52, 62, 63). The present study was designed to test the hypothesis that drinking after a period of chronic water restriction inhibits the activity of hypothalamic magnocellular and specific subpopulations of parvocellular neurons in the PVN that control pituitary-adrenal activity. We have shown that water restriction for 6 days results in increased Fos expression in VP magnocellular and parvocellular neurons but not CRH parvocellular neurons. Because rehydration results in reduced Fos expression in the VP neurons, our results support the hypothesis that water restriction-induced drinking decreases pituitary-adrenal activity by inhibiting neural activity in VP magnocellular and parvocellular neurons. In addition, rehydration in water-restricted rats that have also undergone acute restraint stress reduces plasma ACTH and Fos in VP magnocellular and ...
Behavioral effects of MKC-242 (5-{3-[((2,)-1,4-benzodioxan-2-ylmethyl)amino] propoxy}-1,3-benzodioxole CHl), a novel and selective serotonin 1A receptor agonist, were investigated in rats and mice and compared against those of diazepam, buspirone and tandospirone. MKC-242 (0.0625-0.25 mg/kg, p.o.) significantly increased punished drinking in water-deprived rats. The reference compounds also increased punished drinking at doses of 10 to 40 mg/kg, p.o. The increase by MKC-242 was blocked by N-tert-butyl-3-(4-(2-methoxypenyl)piperazin-1-yl) -2-phenylpropanamide, a serotonin 1A receptor antagonist. MKC-242 (0.1-0.5 mg/kg, p.o.) also increased social interaction under high light and unfamiliar conditions in rats. It had weak benzodiazepine-like side effects in mice. MKC-242 (1, 3 mg/kg, p.o.) attenuated the reduction of locomotion caused by restraint stress in rats, the same effects were observed on both buspirone (100 mg/kg, p.o.) and tandospirone (100 mg/kg, p.o.). In the forced swimming test in ...

The percentage of people with overweight / obesity in the United States has reached very high levels, with 65% of adults over the age of 20 being overweight. Recently, there have been a number of advances in our understanding of the underlying causes of obesity, including greater understanding of both the effects of the environment and effects that are hereditary (i.e., genetic).. One area in which obese versus lean individuals may be different is how their bodies handle water balance and thirst. Studies done in animals suggest that individuals with greater body fat may tolerate periods without water better than lean animals. Thus, at least in animals, others have found a link between ability to tolerate periods without water and increased body weight.. We are studying whether the ability to tolerate periods without water and ability to feel thirst might differ in lean versus obese individuals. To do so, we will ask lean and obese individuals to undergo tests that include a period of ...
The average size horse drinks 10 to 12 gallons of water per day. Draft horses may drink up to 15 to 20 gallons of water a day. A lactating mare or a horse that has sweated a lot will drink more. Cold weather increases feed or energy intake so the horse can tolerate the weather. Many horses consume more hay. Water has a role in moving digesta through the intestine. Lack of fresh, unfrozen water is the number one cause of colic during the winter due to intestinal impaction. One of the worst disasters is if the horse does not have access to water. If a horse cannot drink or the water is frozen, the horse becomes dehydrated. Twenty-four hours of water deprivation can cause a horse to lose 4% of its body weight. Forty-eight hours of water deprivation can cause a horse to lose 6.8% of its body weight and after 72 hours, body weight loss has increased to 9%. Dehydration symptoms may include dry mucous membranes, sunken eyes, slow capillary refill, tucked up appearance and loss of elasticity in skin. ...

Artificially-inseminated New Zealand White rabbits were administered ethylene glycol by gavage on gestational days 6 through 19 at doses of 0, 100, 500, 1000 or 2000 mg/kg/day , with 23-24 inseminated animals per group. Clinical signs were recorded daily during treatment and on gd 25 and 30 (animals were observed at least once daily throughout the study); maternal body weights were recorded on gd 0, 6-19, 25 and 30 and maternal water consumption was measured daily. At necropsy (gd 30), maternal body weight, liver weight, kidney weight and gravid uterine weight were recorded. Kidneys, from 10 animals/dose and all females who died, were examined histologically. Ovarian corpora lutea were counted; uterine implantation sites (total sites, resorptions, dead fetuses and live fetuses) were recorded. All live fetuses were weighed, sexed and examined for external, visceral, craniofacial and skeletal alterations.. EG administered by gavage to pregnant NZW rabbits during major organogenesis resulted in ...

On-farm hatching systems for broiler chicks are increasingly used in practice. We studied whether or not performance, health and welfare aspects differed between commercial flocks hatched on-farm or in a hatchery (control). In two successive production cycles on seven farms, a total of 16 on-farm hatched flocks were paired to 16 control flocks, housed at the same farm. Paired flocks originated from the same batch of eggs and were subjected to similar on-farm management. On-farm hatched and control flocks only differed with respect to hatching conditions, with on-farm hatched flocks not being exposed to, for example, chick handling, post-hatch feed and water deprivation and transport, in contrast to control flocks that were subjected to standard hatchery procedures, subsequently transported and placed in the poultry house. Day-old chick quality (navel and hock scores), 1st week mortality, total mortality, BW at day (d) 0, d7 and at depopulation, and (total) feed conversion ratio were determined. ...

In the last years several researches have shown the extent to which physical activity has been efficient in the treatment and prevention of disease. In the present work we studied biochemical and nutritional parameters that give us a general vision of the benefits of exercise for health. Forty five female Fisher rats were distributed into four groups which were subjected to swimming training in different volumes (30, 60, 120 and 240 minutes) as well as a sedentary group; all animals were fed a commercial ration and received food and water ad libitum. The results showed an increase in food intake, fecal volume and in heart weight as well as a decrease in body weight and in the weight of the finger long extensor and gastrocnemius muscles in the 240 group. In relation to glucose, hemoglobin and albumin an increase was observed in the groups that trained for longer periods (120 and 240 minutes). As for lipid profile, total cholesterol was diminished in the animals that swam 30 minutes. When hepatic ...
Water deprivation test: Patients with NDI tend to produce urine that has a low concentration despite being deprived of water. On administration of AVP, patients with NDI will show little or no increase in urine concentration. During the water deprivation test, the patient is carefully monitored to make sure his or her body weight and blood plasma concentration stay within a safe range. The patient goes without water for less than six hours while the blood plasma concentrations and urine volume are measured. If the patient has NDI, he or she will be resistant to the antidiuretic action of AVP. Immediately following the water deprivation period, a patient with NDI will still have concentrated blood plasma and dilute urine despite the fact that he or she will be fairly dehydrated at that point. At the end of the water fast, the patients response to an infusion of DDAVP is measured. If the patient does not respond to DDAVP, he or she may have NDI. If the patient shows highly concentrated urine in ...

Diabetes mellitus would have shown up on bloodwork if that was the problem. Cushings is also a cause of drinking and peeing a lot, as is prednisone if theyre on it. Theres also a disease called diabetes insipidus that causes them to drink and pee like mad with no bloodwork abnormalities. If all other tests are normal, the next step is to do a water deprivation test to differentiate diabetes insipidus from a behavioral thing. The good news is that its treatable. The bad news is that the hormone to treat it is kinda expensive ...
Mayor Kenneth Cockayne announced today that the Bristol Water Department, as a Department of the City of Bristol, is notifying customers that the citys reservoirs have declined to 70 percent capacity from the lack of rain and that the water department has issued voluntary water restrictions effective immediately.. A lack of rain and unseasonably warm weather over the past few weeks has lowered our reservoirs along with the aquifers that our well fields draw water from to levels that require the Bristol Water Department to request conservation from our customers, said Robert J. Longo, superintendent of the Bristol Water Department in a press release from the city. Longo added, Earlier this week, the Bristol Water Department reached out to our larger users including the Parks Department, Public Works, Fire Department, Board of Education, Pequabuck and Chippanee golf courses, ESPN, St Paul Catholic High School, and Lake Compounce asking for their cooperation in reducing usage at their ...
With the last significant rainfall in the Shoalhaven catchment occurring in June, the natural flows in the Shoalhaven River have dropped to below 90 megalitres per day and water restrictions may be necessary in the next month. The previous water restrictions were removed in December 2018 following significant rainfall and with regular falls since that time, there has been no need to impose restrictions. This is despite the drought conditions being experienced in other parts of NSW. Water restrictions are imposed in line with the Shoalhaven Drought Management Plan and are triggered by the first release of water from the backup storage at Danjera Dam. This first release occurs when Councils off-stream storage drops to 60% capacity, it currently sits at 87%.. The Acting Director of Shoalhaven Water Mr Robert Horner said, the total combined Shoalhaven dam storage level is at 85% of capacity and the outlook for rain in the near future is not strong. We are therefore preparing for water restrictions ...
Adapting temperate fruit-tree cultivation to stressful environments is a considerable challenge for the breeder. This is especially true for water restriction (WR) which is likely to occur more frequently in the near future, not only in Mediterranean climates but also in several parts of the middle and high latitudes. Apple was chosen as an example of fruit tree distributed worldwide and also cultivated in semi-arid regions where irrigation is crucial for regular cropping. A range of apple genotypes sourced from a single-cross-population and trained as grafted one-year-old single shoots, grown in 4-L pots in controlled conditions were used. We investigated genotype variations in some morphological and leaf ecophysiological traits of shoots maintained in a severe WR in comparison to well-watered (WW) shoots. A Principal Component Analysis performed on all variables showed that the effects of WR on the two components of vegetative growth (i.e., stem and leaf) and on leaf ecophysiology strongly ...

Background:. Plasma arginine vasopressin (AVP) measurement is recommended for the differential diagnosis of diabetes insipidus and polydipsia. However, AVP measurement is cumbersome. AVP is derived from a larger precursor peptide along with copeptin, which is a more stable peptide directly mirroring the production of AVP. Copeptin can be assayed readily in plasma.. Aim: To evaluate the diagnostic accuracy of copeptin levels in the diagnosis and differential diagnosis of diabetes insipidus.. Design: Prospective, observational multicenter study.. Setting: Department of Endocrinology, University Hospital of Basel. Patients: Patients with suspected or known central (complete or partial), nephrogenic (complete or partial) or psychogenic diabetes insipidus undergoing a standardized water deprivation test.. Intervention: All patients with suspected or known diabetes insipidus will undergo an overnight water deprivation test and a standardized water deprivation test, as routinely performed in the ...
Two brothers, patient 1 with fever and vomiting, and patient 2 with failure to gain weight were studied. After 4 hr of water deprivation test, the urinary osmolality of the patient 1 was only 105 mOsm/liter and his body weight showed a 4.6% reduction. In response to desamino-8-D arginine vasopressin intranasal administration, no significant elevation of urinary osmolality of patient 1 occurred. After low dose vasopressin tests, the maximal urinary osmolality of their father was in the normal range, but that of their mother was below the normal range. Moreover, the patients showed no significant increase of urinary osmolality after the same tests. The brothers were diagnosed as nephrogenic diabetes insipidus (NDI) and their mother was diagnosed as a carrier. An early diagnosis of NDI is important, since adequate managements such as low-solute diet with restricted protein and salt intake or such as water intake at frequent intervals can prevent the hyperosmolality which would develop the delayed mental
A water deprivation test involves not drinking any liquid for several hours to see how your body responds. If you have diabetes insipidus, youll continue to pass large amounts of dilute urine, when normally youd only pass a small amount of concentrated urine.. During the test, the amount of urine you produce will be measured. You may also need a blood test to assess the levels of antidiuretic hormone (ADH) in your blood.. Your blood and urine may also be tested for substances such as glucose (blood sugar), calcium and potassium. If you have diabetes insipidus, your urine will be very dilute, with low levels of other substances. A large amount of sugar in your urine may be a sign of type 1 or type 2 diabetes rather than diabetes insipidus.. ...
This study investigated the effects of excess cortisol on physiological mechanisms that resist dehydration in Bos indicus steers (n = 31, 2 yr of age, 193 ± 21.47 kg mean BW) during a 90-h period. Steers were assigned randomly to one of four groups: 1) no water/no cortisol (n = 8), 2) water/no cortisol (n = 8), 3) no water/cortisol (n = 8), and 4) water/cortisol (n = 7). Animals allocated to cortisol treatment groups were given 0.1 mg•kg BW-1•h-1 of hydrocortisone suspended in isotonic saline for the duration of the study. Total body water, osmolality, hematocrit, urine output, feed and water intake, and plasma concentrations of arginine vasopressin (AVP), angiotensin II (AII), electrolytes, total protein, and albumin were determined at 24-h intervals for 90 h. In the presence of excess plasma cortisol, total body water was maintained in the presence of a water deprivation insult for 90 h, whereas hydration indices, such as total plasma protein and albumin, did not change, supporting the ...
We investigated the physiological and behavioural strategies by which lactating Ethiopian Somali goats endure repeated periods of water deprivation. The experiment lasted for 32 days and was divided into four periods of 8 days each. Measurements were taken during the first 4 days in each period. Seven does (W1) were watered once daily and seven does (W4) were watered once every 4th day. Rectal temperature was taken at 0800 and 1715 h. Blood samples were taken in the evening and milk samples in the morning. The goats were on pasture between 0900 to 1215 h and 1315 to 1630 h with behaviour recorded every 5 min. The does were supplemented with 300 g of concentrates per head per day. Plasma and milk osmolality were determined by freezing point depression. Plasma total protein was measured on a TS refractometer. Plasma vasopressin concentrations were analysed by radio-immunoassay. The mean daily water intake of W1 was 1897 ml compared with the calculated mean of 1075 ml in W4 (P , 0.001). The mean ...
Rice (Oryza sativa) is a water guzzler when compared to other crops. It typically uses up to three times more water than other food crops such as maize or wheat and consumes around 30 percent of the fresh water used for crops worldwide. In conditions where water is scarce, it is important to have crops that can efficiently generate biomass (plant tissue) using limited amounts of water. HARDY rice shows a significant increase in biomass under both drought and non-drought conditions. The researchers found that the biomass of HARDY rice increased by around 50 percent under conditions of water deprivation (drought) compared to the unmodified version of the same type of rice ...

In plants, many cuticle-associated mutants have been reported (Kosma and Jenks, 2007), but none of these exhibited reduced transpiration rates, improved WUE, and elevated tolerance to drought-like conditions. The cer9 mutant reported here shows delayed leaf wilting when exposed to increasing water deprivation, which was associated with reduced whole plant transpiration rates regardless of whether stomata were open (in the light) or closed (in the dark). Moreover, the cer9 mutant had higher WUE (less-negative δ13C), while no other cuticle mutants we examined here (even those with known cuticle permeability defects) showed any change in WUE. Besides a dramatic elevation in the VLCFA pool of the cuticular waxes of the cer9 mutant, cer9 also possessed major changes in the cutin monomer composition and a highly modified cuticle membrane ultrastructure. The total cutin monomer amount on the stem of cer9 was 1.6-fold greater than on the wild type, and the stem cuticle membrane thickness was comparably ...
In the camel, it has also been demonstrated that the daily Ta cycle is able to entrain the master circadian clock, thus highlighting that Ta is a true zeitgeber (El Allali et al. 2013). The protocol validated in this study will also permit to test in these specific conditions, if the zeitgeber effect of Ta cycle with higher amplitude is able, as suggested by (El Allali et al. 2013), to counteract the zeitgeber effect of the light-dark cycle, a fundamental question in mammalian circadian biology. It will also lead to determine more precisely the functioning of the master clock and the circadian network in dehydrated and heat‐stressed camels.. The use of data loggers over a long period of time has also facilitated understanding the interpretation of (Al‐Haidary 2005). In the present work, we observed that the increase in amplitude of Tb starts after 7 days under heat stress and water deprivation. In the work of (Al‐Haidary 2005), the analysis was only done after 4 days and the protocol used ...
The Gore District Council is urging Mataura residents not to get too complacent about water use just yet with recent rainfall not enough to sustain water levels in the towns reservoir.. 3 Waters Asset Manager Matt Bayliss said the water flow into the Pleura Dam has dropped off quicker than expected after the rainfall a couple of weeks ago.. There was a significant increase in flow into the dam but it has dropped over the weekend so we are struggling to keep up with demand.. The Council eased water restrictions from level 4 to level 2 last week, and stopped emergency pumping from the Mataura River for Gore and Mataura.. Mr Bayliss warned that water restrictions may need to be lifted, and emergency pumping resumed, in Mataura if there was no decent rainfall over the next few days.. We will be closely monitoring the dam levels and water consumption during the week.. Commercial water tankers have not been allowed to take water from the towns supply since last month. This would continue for the ...
The principal objective of this study was to develop an alternative non-genetic rat model for type 2 diabetes (T2D). Six-week-old male Sprague-Dawley rats (190.56 ± 23.60g) were randomly divided into six groups namely: Normal Control (NC), Diabetic/Streptozotocin Control (STZ), Fructose-10 (FR10+STZ), Fructose-20 (FR20+STZ), Fructose-30 (FR30+STZ) and Fructose-40 (FR40+STZ) and were fed a normal rat pellet diet ad libitum for 2 weeks. During this period, the two control groups received normal drinking water whilst the fructose groups received 10, 20, 30 and 40% fructose in drinking water ad libitum respectively. After two weeks of dietary manipulation, all groups except the NC group received a single injection (i.p.) of streptozotocin (STZ) (40mg/kg BW) dissolved in citrate buffer (pH 4.4). The NC group received only a vehicle buffer injection (i.p.). One week after the STZ injection, animals with non-fasting blood glucose ,300 mg/dl were considered as diabetic. Three weeks after the STZ ...
Twenty-seven adult albino rats of local strain, of body weight ranging between 150 and 200 g at the beginning of this study, were used. The age of these rats was about 8-10 weeks at the start of the experimental work. They were housed in groups in cages (20 cm width×32 cm length×20 cm height) at room temperature with natural light/dark cycles for 1 week to acclimatize them to lab conditions. Rats were fed a standard diet of commercial rat chow (El-Gomhoria Company, Cairo, Egypt) and tap water ad libitum until the time of the experiment [6]. During the acclimatization period, daily food intake was measured to know the mean daily food intake per rat. The rats were divided into three equal groups: (a) control sham-operated group, (b) ovariectomized nontreated group, and (c) ovariectomized treated group. The animals were accustomed to the injection procedure by intraperitoneal injection with saline (0.5 ml/rat) for 2 days before PYY3-36 administration [7]. Next, each rat received PYY3-36 (Sigma ...

Rats weighed 180 to 200 g at the time of necropsy.. Inhalation ...
Sprague Dawley rats were used in all experiments and were treated in accordance with the guidelines set by the National Institutes of Health for the humane treatment of animals. Attempts were made to minimize the number of animals used. Animals had access to food and water ad libitum; they were housed with their litter until weaning at postnatal day 21 (P21), after which they were grouped in plastic cages under diurnal lighting conditions with 12 hr on and 12 hr off. In all experiments, littermates were randomly assigned to either the experimental or control groups. Experimental and control animals remained together with the dam until weaning.. Sixteen rats were used for a pilot study of 5-bromo-2′-deoxyuridine-5′-monophosphate (BrdU) dosage and 126 immature rats [experimental (exp.), n = 63; control (con.),n = 63] were used for the time course study of neurogenesis in immature rats.

Animals and surgery. Young adult female Sprague Dawley rats (B & K Universal, Stockholm, Sweden), weighing 200-250 gm at the beginning of the experiment, were housed under a 12 hr light/dark cycle with access to food and water ad libitum. Two stereotaxic injections of 6-OHDA were made under equithesin anesthesia into the right striatum using a 10 μl Hamilton microsyringe fitted with a 26 gauge steel cannula. A total amount of 6-OHDA (20 μg) dissolved in 4 μl of 0.2 mg/mll-ascorbate-saline (10 μg in 2 μl per site) was injected at the following coordinates (in mm, with reference to bregma and dura): (1) anterior-posterior, 0.5; lateral, −2.5; and ventral, −5.0 [tooth bar (TB), 0] and (2) anterior-posterior, −0.5; lateral, −4.2; and ventral, −5.0 (TB, 0). The injection rate was 1 μl/min, and the cannula was left in place for additional 2 min before slowly retracting it.. During the same surgery session, animals received implants of 22 gauge guide cannulae (Plastics One, Roanoke, VA) ...

What are we going to do once all the water is gone? Thanks to the worst drought in more than 1,000 years, the western third of the country is facing the greatest water crisis that the United States has ever seen. Lake Mead is now the lowest that it has ever been since the Hoover Dam was finished in the 1930s, mandatory water restrictions have already been implemented in the state of California, and there are already widespread reports of people stealing water in some of the worst hit areas. But this is just the beginning. Right now, in a desperate attempt to maintain somewhat normal levels of activity, water is being pumped out of the ground in the western half of the nation at an absolutely staggering pace. Once that irreplaceable groundwater is gone, that is when the real crisis will begin. If this multi-year drought stretches on and becomes the megadrought that a lot of scientists are now warning about, life as we know it in much of the country is going to be fundamentally transformed and ...
