A small amount of methemoglobin is present in the blood normally, but injury or toxic agents convert a larger proportion of hemoglobin into methemoglobin, which does not function reversibly as an oxygen carrier. Methemoglobinemia may be due to a defect in the enzyme NADH methemoglobin reductase (an autosomal recessive trait) or to an abnormality in hemoglobin M (an autosomal dominant trait). (Dorland, 27th ed)Peptides: Members of the class of compounds composed of AMINO ACIDS joined together by peptide bonds between adjacent amino acids into linear, branched or cyclical structures. OLIGOPEPTIDES are composed of approximately 2-12 amino acids. Polypeptides are composed of approximately 13 or more amino acids. PROTEINS are linear polypeptides that are normally synthesized on RIBOSOMES.Peptide Fragments: Partial proteins formed by partial hydrolysis of complete proteins or generated through PROTEIN ENGINEERING techniques.Peptide Library: A collection of cloned peptides, or chemically synthesized peptides, frequently consisting of all possible combinations of amino acids making up an n-amino acid peptide.Antimicrobial Cationic Peptides: Small cationic peptides that are an important component, in most species, of early innate and induced defenses against invading microbes.

It can cause NATRIURESIS; DIURESIS; VASODILATION; and inhibits secretion of RENIN and ALDOSTERONE. It improves heart function. It contains 32 AMINO ACIDS.Theca Cells: The flattened stroma cells forming a sheath or theca outside the basal lamina lining the mature OVARIAN FOLLICLE. Thecal interstitial or stromal cells are steroidogenic, and produce primarily ANDROGENS which serve as precusors of ESTROGENS in the GRANULOSA CELLS.Ovarian Follicle: An OOCYTE-containing structure in the cortex of the OVARY. The oocyte is enclosed by a layer of GRANULOSA CELLS providing a nourishing microenvironment (FOLLICULAR FLUID). The number and size of follicles vary depending on the age and reproductive state of the female. The growing follicles are divided into five stages: primary, secondary, tertiary, Graafian, and atretic. Follicular growth and steroidogenesis depend on the presence of GONADOTROPINS.Hair Follicle: A tube-like invagination of the EPIDERMIS from which the hair shaft develops and into which SEBACEOUS GLANDS open. The hair follicle is lined by a cellular inner and outer root sheath of epidermal origin and is invested with a fibrous sheath derived from the dermis. (Stedman, 26th ed) Follicles of very long hairs extend into the subcutaneous layer of tissue under the SKIN.Follicle Stimulating Hormone: A major gonadotropin secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Follicle-stimulating hormone stimulates GAMETOGENESIS and the supporting cells such as the ovarian GRANULOSA CELLS, the testicular SERTOLI CELLS, and LEYDIG CELLS. FSH consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the three pituitary glycoprotein hormones (TSH, LH, and FSH), but the beta subunit is unique and confers its biological specificity.Granulosa Cells: Supporting cells for the developing female gamete in the OVARY. They are derived from the coelomic epithelial cells of the gonadal ridge. Granulosa cells form a single layer around the OOCYTE in the primordial ovarian follicle and advance to form a multilayered cumulus oophorus surrounding the OVUM in the Graafian follicle. The major functions of granulosa cells include the production of steroids and LH receptors (RECEPTORS, LH).Ovary: The reproductive organ (GONADS) in female animals. In vertebrates, the ovary contains two functional parts: the OVARIAN FOLLICLE for the production of female germ cells (OOGENESIS); and the endocrine cells (GRANULOSA CELLS; THECA CELLS; and LUTEAL CELLS) for the production of ESTROGENS and PROGESTERONE.Ovulation: The discharge of an OVUM from a rupturing follicle in the OVARY.Androstenedione: A delta-4 C19 steroid that is produced not only in the TESTIS, but also in the OVARY and the ADRENAL CORTEX. Depending on the tissue type, androstenedione can serve as a precursor to TESTOSTERONE as well as ESTRONE and ESTRADIOL.Follicular Fluid: The fluid surrounding the OVUM and GRANULOSA CELLS in the Graafian follicle (OVARIAN FOLLICLE). The follicular fluid contains sex steroids, glycoprotein hormones, plasma proteins, mucopolysaccharides, and enzymes.Progesterone: The major progestational steroid that is secreted primarily by the CORPUS LUTEUM and the PLACENTA. Progesterone acts on the UTERUS, the MAMMARY GLANDS and the BRAIN. It is required in EMBRYO IMPLANTATION; PREGNANCY maintenance, and the development of mammary tissue for MILK production. Progesterone, converted from PREGNENOLONE, also serves as an intermediate in the biosynthesis of GONADAL STEROID HORMONES and adrenal CORTICOSTEROIDS.

Isoleucine-15 of rainbow trout carbonyl reductase-like 20beta-hydroxysteroid dehydrogenase is critical for coenzyme (NADPH) binding. (1/27)

Carbonyl reductase-like 20beta-hydroxysteroid dehydrogenase (CR/20beta-HSD) is an enzyme that converts 17alpha-hydroxyprogesterone to 17alpha, 20beta-dihydroxy-4-pregnen-3-one (the maturation-inducing hormone of salmonid fish). We have previously isolated two types of CR/20beta-HSD cDNAs from ovarian follicle of rainbow trout (Oncorhynchus mykiss). Recombinant proteins produced by expression in Escherichia coli in vitro showed that one (type A) had CR and 20beta-HSD activity but that the other (type B) did not. Among the three distinct residues between the protein products encoded by the two cDNAs, two residues (positions 15 and 27) are located in the N-terminal Rossmann fold, the coenzyme binding site. To investigate the structure/function relationships of CR/20beta-HSDs, we generated mutants by site-directed mutagenesis at the following positions: MutA/I15T, MutB/T15I, and MutB/Q27K. Enzyme activity of wild-type A was abolished by substitution of Ile-15 by Thr (MutA/I15T). Conversely, enzyme activity was acquired by the replacement of Thr-15 with Ile in type B (MutB/T15I). MutB/T15I mutant showed properties similar to the wild-type A in every aspect tested. Mutation MutB/Q27K had only partial enzyme activity, indicating that Ile-15 plays an important role in enzyme binding of cofactor NADPH.  (+info)

Affinity labeling of steroid binding sites. Study of the active site of 20beta-hydroxysteroid dehydrogenase with 2alpha-bromoacetoxyprogesterone and 11alpha-bromacetoxyprogesterone. (2/27)

To further characterize the active site of 20beta-hydroxysteroid dehydrogenase (EC 1.1.1.53) from Streptomyced hydrogenans we synthesized 2alpha-bromoacetoxyprogesterone, a substrate for the enzyme in 0.05 M phosphate buffer at 25 degrees, pH 7.0, with Km and Vmax values of 1.90 X 10(-5) M and 6.09 nmol/min/mg of enzyme, respectively. This affinity labeling steroid inactivates 20beta-hydroxysteroid dehydrogenase in an irreversible and time-dependent manner which follows pseudo-first order kinetics with a t1/2 value of 4.6 hours. 2alpha-[2-3H]Bromoacetoxyprogesterone was synthesized and used to radiolabel the enzyme active site. Amino acid analysis of the acid hydrolysate of the radiolabeled enzyme supports a mechanism whereby the steroid moiety delivers the alkylating group to the steroid binding site of the enzyme where it reacts with a methionyl residue. Both 2alpha- and 11alpha-bromoacetoxyprogesterone alkylate a methionyl residue at the active site of 20beta-hydroxysteroid dehydrogenase. The enzyme was inactivated with a mixture containing both 2alpha-[2-3H]Bromoacetoxyprogesterone and 11alpha-2[2-14C]bromoacetoxyprogesterone. Following degradation of separate aliquots of the radiolabeled enzyme by cyanogen bromide or trypsin, the protein fragments were separated by gel filtration and ion exchange chromatography. Resolution of peptides carrying the 3H label from those possessing the 14C label demonstrates that 2alpha-bromoacetoxyprogesterone and 11alpha-bromoacetoxyprogesterone each label a different methionine at the steroid binding site of 20beta-hydroxysteroid dehydrogenase.  (+info)

Teleost ovarian carbonyl reductase-like 20beta-hydroxysteroid dehydrogenase: potential role in the production of maturation-inducing hormone during final oocyte maturation. (3/27)

17alpha,20beta-Dihydroxy-4-pregnen-3-one is the major oocyte maturation-inducing hormone of several teleost species. Gonadotropin-induced increase in ovarian 20beta-hydroxysteroid dehydrogenase activity is essential for the synthesis of maturation-inducing hormone. Cloning and expression studies suggest that ayu (Plecoglossus altivelis) ovarian carbonyl reductase can function as 20beta-hydroxysteroid dehydrogenase. The amino acid sequence deduced from the isolated cDNA had 276 amino acid residues and shared approximately 60% homology with mammalian and teleostean carbonyl reductases. The sequence data search showed that the ayu cDNA clone belongs to the short-chain dehydrogenase/reductase family. The clear lysate prepared from Escherichia coli harboring the cDNA catalyzed the production of maturation-inducing hormone. Its identification was confirmed by two-dimensional, thin-layer chromatography followed by recrystallization. Purification of the E. coli-expressed cDNA product revealed that it possessed both carbonyl reductase and steroid dehydrogenase activities, and 17alpha-hydroxyprogesterone, the endogenous immediate precursor of maturation-inducing hormone, was one of the preferred substrates. Furthermore, Northern blot analysis denoted that the transcripts are present both in fully grown, immature ovarian follicles and at higher levels in mature ovarian follicles. These results demonstrate that the carbonyl reductase of ayu ovary is involved in the production of maturation-inducing hormone, and they provide evidence for a novel physiological role of this enzyme in the final maturation of oocytes. Based on its functional properties, the enzyme can be referred to as carbonyl reductase-like 20beta-hydroxysteroid dehydrogenase.  (+info)

Ovarian carbonyl reductase-like 20beta-hydroxysteroid dehydrogenase shows distinct surge in messenger RNA expression during natural and gonadotropin-induced meiotic maturation in nile tilapia. (4/27)

Meiotic maturation in fish is accomplished by maturation-inducing hormones. 17alpha,20beta-Dihydroxy-4-pregnen-3-one (17alpha,20beta-DP) was identified as the maturation-inducing hormone of several teleosts, including Nile tilapia. A cDNA encoding 20beta-hydroxysteroid dehydrogenase (20beta-HSD), the enzyme that converts 17alpha-hydroxyprogesterone to 17alpha,20beta-DP, was cloned from the ovarian follicle of Nile tilapia. Genomic Southern analysis indicated that 20beta-HSD probably exists as a single copy in the genome. The Escherichia coli-expressed cDNA product oxidized both carbonyl and steroid compounds, including progestogens, in the presence of NADPH. Carbonyl reductase-like 20beta-HSD is broadly expressed in various tissues of tilapia, including ovary, testis, and gill. Northern blot and reverse transcription polymerase chain reaction analyses during the 14-day spawning cycle revealed that the expression of 20beta-HSD in ovarian follicles is low from Day 0 to Day 8 after spawning and is not detectable on Day 11. Distinct expression was evident at Day 14, the day of spawning. In males, 20beta-HSD expression was observed continually in mature testes but not in immature testes of 30-day-old fish. In vitro incubation of postvitellogenic immature follicles (corresponding to Day 11 after spawning) with hCG induced the expression of 20beta-HSD mRNA transcripts within 1-2 h, followed by the final meiotic maturation of oocytes. In tissues such as gill, muscle, brain, and pituitary, however, hCG treatment did not induce any changes in the levels of mRNA transcripts. Actinomycin D blockade of hCG-induced 20beta-HSD expression and final oocyte maturation demonstrated the involvement of transcriptional factors. The carbonyl reductase-like 20beta-HSD plays an important role in the meiotic maturation of tilapia gametes.  (+info)

An aldose reductase with 20 alpha-hydroxysteroid dehydrogenase activity is most likely the enzyme responsible for the production of prostaglandin f2 alpha in the bovine endometrium. (5/27)

Prostaglandins are important regulators of reproductive function. In particular, prostaglandin F2 alpha (PGF(2 alpha)) is involved in labor and is the functional mediator of luteolysis to initiate a new estrous cycle in many species. These actions have been extensively studied in ruminants, but the enzymes involved are not clearly identified. Our objective was to identify which prostaglandin F synthase is involved and to study its regulation in the endometrium and in endometrial primary cell cultures. The expression of all previously known prostaglandin F synthases (PGFSs), two newly discovered PGFS-like genes, and a 20 alpha-hydroxysteroid dehydrogenase was studied by Northern blot and reverse transcription PCR. These analyses revealed that none of the known PGFS or the PGFS-like genes were significantly expressed in the endometrium. On the other hand, the 20 alpha-hydroxysteroid dehydrogenase gene was strongly expressed in the endometrium at the time of luteolysis. The corresponding recombinant enzyme has a K(m) of 7 microM for PGH(2) and a PGFS activity higher than the lung PGFS. This enzyme has two different activities with the ability to terminate the estrous cycle; it metabolizes progesterone and synthesizes PGF(2 alpha). Taken together, these data point to this newly identified enzyme as the functional endometrial PGFS.  (+info)

Pig testicular 20 beta-hydroxysteroid dehydrogenase exhibits carbonyl reductase-like structure and activity. cDNA cloning of pig testicular 20 beta-hydroxysteroid dehydrogenase. (6/27)

cDNA inserts encoding 20 beta-hydroxysteroid dehydrogenase (EC 1.1.1.53) were, for the first time, isolated and cloned from a pig testis cDNA library using synthetic oligonucleotides deduced from the partially determined amino acid sequences. The cDNA contains an open reading frame predicted to encode 289 amino acid residues. Surprisingly, it has 85% amino acid homology to human carbonyl reductase. The purified enzyme exhibited carbonyl reductase activity. Adenine-rich sequence was located in the 3'-untranslated nine-rich sequence was located in the 3'-untranslated region, which may mean that the gene originates by retroposition. RNA transcripts of 1.3, 3, and 6 kilobases were detected in poly(A)+ RNA extracted from pig testis by Northern blot hybridization. The steady-state level of the RNA species increased to a maximum in testes from 10-day-old pigs, but rapidly declined thereafter to the same levels found in testes of mature animals.  (+info)

Short-chain dehydrogenases. Proteolysis and chemical modification of prokaryotic 3 alpha/20 beta-hydroxysteroid, insect alcohol and human 15-hydroxyprostaglandin dehydrogenases. (7/27)

Prokaryotic 3 alpha/20 beta-hydroxysteroid dehydrogenase exhibits one segment sensitive to proteolysis with Glu-C protease and trypsin (cleaving after Glu192 and Arg196, respectively). Cleavage is associated with dehydrogenase inactivation; the presence of NADH offers almost complete protection and substrate (cortisone) gives some protection. Distantly related insect alcohol dehydrogenase is more resistant to proteolysis, but cleavage in a corresponding segment is detectable with Asp-N protease (cleaving before Asp198), while a second site (at Glu243) is sensitive to cleavage with both Glu-C and Asp-N proteases. Combined, the results suggest the presence of limited regions especially sensitive to proteolysis and the possibility of some association between the enzyme active site and the sensitive site(s). Modification of the hydroxysteroid dehydrogenase with tetranitromethane is paralleled by enzyme inactivation. With a 10-fold excess of reagent, labeling corresponds to 1.2 nmol Tyr/nmol protein chain and is recovered largely in Tyr152, with lesser amounts in Tyr251. Tetranitromethane also rapidly inhibits the other two dehydrogenases, but they contain Cys residues, preventing direct correlation with Tyr modification. Together, the proteolysis and chemical modifications highlight three segments of short-chain dehydrogenase subunits, one mid-chain, containing Tyr152 of the steroid dehydrogenase (similar numbers in the other enzymes), strictly conserved and apparently close to the enzyme active site, the other around position 195, sensitive to proteolysis and affected by coenzyme binding, while the third is close to the C-terminus.  (+info)

Cooperativity between 11beta-hydroxysteroid dehydrogenase type 1 and hexose-6-phosphate dehydrogenase in the lumen of the endoplasmic reticulum. (8/27)

The functional coupling of 11beta-hydroxysteroid dehydrogenase type 1 and hexose-6-phosphate dehydrogenase was investigated in rat liver microsomal vesicles. The activity of both enzymes was latent in intact vesicles, indicating the intraluminal localization of their active sites. Glucose-6-phosphate, a substrate for hexose-6-phosphate dehydrogenase, stimulated the cortisone reductase activity of 11beta-hydroxysteroid dehydrogenase type 1. Inhibition of glucose-6-phosphate uptake by S3483, a specific inhibitor of the microsomal glucose-6-phosphate transporter, decreased this effect. Similarly, cortisone increased the intravesicular accumulation of radioactivity upon the addition of radiolabeled glucose-6-phosphate, indicating the stimulation of hexose-6-phosphate dehydrogenase activity. A correlation was shown between glucose-6-phosphate-dependent cortisone reduction and cortisone-dependent glucose-6-phosphate oxidation. The results demonstrate a close cooperation of the enzymes based on co-localization and the mutual generation of cofactors for each other.  (+info)

Cortisone injections are administered to people that suffer from joint pain and inflammation. Although cortisone shots can help manage pain, they also produce some side effects. Read on for more details into the potential risks of cortisone shots.
I know cortisone shots are not good for you, but for the medical peeps, do you know if an ER or urgent care would give a cortisone shot? Between what Im experiencing and discussion with my PT over a week ago. Im pretty sure I have ischial bursitis syndrome on the right and I can hardly sit at this point. The exercises he gave me and icing and ibu are doing nothing, I dont know when Ill be able to get into a doc, and I have an 8-hr ride in my future come Thursday. Im grasping at straws, but I dont want to spend the $$ for an ER / urgent care visit if theyre going to tell me they cant do anything.. Let me add, where I live it can up to 2 to 4 weeks to get into a doctor, unless its your primary. ...

I thought I had heard all there was to PE, but I was wrong. Someone at another board posted a long time ago (2008) that he had a surgeon inject cortisone into the "undisturbed portion of his ligs." "He said I could still gain EL and the cortisone would help loosen things up and make it easier to gain." He didnt say much about his experience, though.. Anyone knows anything about this? I wonder if anyone could have this done to enhance gains by hanging and stretching? Does it make sese, medically speaking? I dont know much about cortisone to know ...

The day when sufficient follicle maturation is observed you will be informed of the exact time for your last injection which will induce final oocyte maturation and ovulation (Pregnyl or Profasi or Ovitrelle) as well as the dose that must be used. This injection is human chorionic gonadotrophin which mimics the LH action and induces final oocyte maturation and ovulation. The injection is administered late in the evening or after midnight. Ovulation is expected about 36 hours later.. This last injection concludes the painful phase of daily injections and marks the end of GnRH analogue and gonadotrophin administration. The following day is a day to rest and prepare for the egg collection. This last injection is very particular in that it must be done at a very specific time, which will be the deciding factor for the time of egg collection. If we attempt to retrieve the eggs before they develop completely, i.e. much earlier than 36 hours after the injection, we shall collect immature eggs. On the ...

DEAR DR. DONOHUE: I have a question that I have been puzzling over for some time, and I would love your opinion on it. I have known many people who were on prednisone. At first it is a wonder drug, and they feel fine. After they are on it for some time, problems and side effects start to appear.Why is this drug prescribed so often? Are there alternatives? I feel like I should wear a bracelet that states never to give me prednisone. - M.J.Prednisone is one of the drugs in the large cortisone
The post-vitellogenic oocytes of teleost fish are generally unresponsive to maturation-inducing hormone (MIH) until a luteinizing hormone (LH) surge stimulates sensitivity via the acquisition of oocyte-maturational competence (OMC). Heterologous gap junctions (GJs) between granulosa cells and the oocyte have been previously implicated in the regulation of oocyte maturation in various vertebrate species. Although heterologous GJ are present in ovarian follicles of ayu (Plecoglossus altivelis), their role in maturation remains unclear. In the present study, we cloned and characterized complementary DNAs for GJ protein connexin (Cx), and examined the expression pattern of Cx messenger RNAs in the ayu ovary. Four Cx cDNAs with predicted molecular masses of 32.1 (Cx32.1), 34.9 (Cx34.9), 44.1 (Cx44.1), and 44.2 (Cx44.2) kDa, respectively, were cloned. Northern blot analysis revealed that the levels of Cx44.1 and Cx44.2 transcripts were similar during the vitellogenic and ovulatory stages. Cx32.1 transcripts

PY - 2013. Y1 - 2013. N2 - Steroid hormones trigger the onset of sexual maturation in animals by initiating genetic response programs that are determined by steroid pulse frequency, amplitude and duration. Although steroid pulses coordinate growth and timing of maturation during development, the mechanisms generating these pulses are not known. Here we show that the ecdysone steroid pulse that drives the juvenile-adult transition in Drosophila is determined by feedback circuits in the prothoracic gland (PG), the major steroid-producing tissue of insect larvae. These ...
The biological activity of steroid hormones is regulated at the pre-receptor level by several enzymes including 17 beta-hydroxysteroid dehydrogenases (17 beta -HSD). The latter are present in many microorganisms, invertebrates and vertebrates. Dysfunctions in human 17 beta-hydroxysteroid dehydrogenases result in disorders of biology of reproduction and neuronal diseases, the enzymes are also involved in the pathogenesis of various cancers. 17 beta-hydroxysteroid dehydrogenases reveal a remarkable multifunctionality being able to modulate concentrations not only of steroids but as well of fatty and bile acids. Current knowledge on genetics, biochemistry and medical implications is presented in this review.

If your blood sugar gets too low, you may feel weak, drowsy, confused, anxious, or very hungry. You may also sweat, shake, or have blurred vision, a fast heartbeat, or a headache that will not go away. If you have symptoms of low blood sugar (hypoglycemia), check your blood sugar. If your blood sugar is 70 mg/dL (milligrams per deciliter) or below, do one of the following: Drink 4 ounces (one-half cup) of fruit juice, or eat 5 to 6 pieces of hard candy, or take 2 to 3 glucose tablets. Recheck your blood sugar 15 minutes later. If your blood sugar goes above 70 mg/dL, eat a snack or a meal. If your blood sugar is still below 70 mg/dL, drink one-half cup juice, or eat 5 to 6 pieces of candy, or take 2 to 3 glucose tablets. Carry candy or some type of sugar with you at all times, especially if you are away from home. You can take this if you feel that your blood sugar is too low, even if you do not have a blood glucose meter. Always carefully follow your doctors instructions about how to treat ...

17 beta-hydroxysteroid dehydrogenases catalyze the oxidoreduction of hydroxy/oxo groups at position C17 of steroid hormones, thereby constituting a prereceptor control mechanism of hormone action. At present, 11 different mammalian 17 beta-hydroxysteroid dehydrogenases have been identified, catalyzing the cell- and steroid-specific activation and inactivation of estrogens and androgens. The human type 10 17 beta-hydroxysteroid dehydrogenase (17 beta-HSD-10) is a multifunctional mitochondrial enzyme that efficiently catalyzes the oxidative inactivation at C17 of androgens and estrogens. However, it also mediates oxidation of 3 alpha-hydroxy groups of androgens, thereby reactivating androgen metabolites. Finally, it is involved in beta-oxidation of fatty acids by catalyzing the L-hydroxyacyl CoA dehydrogenase reaction of the beta-oxidation cycle. These features and expression profiles suggest a critical role of 17 beta-HSD-10 in neurodegenerative and steroid-dependent cancer forms. Since no three

Glucocorticoid hormones play essential roles in adaptation to stress, regulation of metabolism and inflammatory responses. Their effects primarily depend on their binding to intracellular receptors leading to altered target gene transcription as well as on cell-type specific biotransformation between 11beta-hydroxy glucocorticoids and their 11-oxo metabolites. The latter effect is accomplished by two different 11beta-hydroxysteroid dehydrogenase isozymes, constituting a shuttle system between the receptor ligand cortisol and its non-binding precursor cortisone. Whereas the type 1 enzyme (11beta-HSD1) is in vitro a NADP(H)- dependent bidirectional enzyme, it reduces in most instances in vivo cortisone to active cortisol. The type 2 enzyme is an exclusive NAD+ dependent dehydrogenase of glucocorticoids, thus protecting the mineralocorticoid receptor against illicit occupation by cortisol. Inhibition of tissue-specific glucocorticoid activation by 11beta-HSD1 constitutes a promising target in the
17Beta-hydroxysteroid dehydrogenases (17beta-HSDs) catalyze the NAD(P)(H) dependent oxidoreduction at C17 oxo/beta-hydroxyl groups of androgen and estrogen hormones. This reversible reaction constitutes an important pre-receptor control mechanism for nuclear receptor ligands, since the conversion switches between the 17beta-OH receptor ligands and their inactive 17-oxo metabolites. At present, 14 mammalian 17beta-HSDs are described, of which at least 11 exist within the human genome, encoded by different genes. The enzymes differ in their expression pattern, nucleotide cofactor preference, steroid substrate specificity and subcellular localization, and thus constitute a complex system ensuring cell-specific adaptation and regulation of sex steroid hormone levels. Broad and overlapping substrate specificities with enzymes involved in lipid metabolism suggest interactions of several 17beta-HSDs with other metabolic pathways. Several 17beta-HSDs enzymes constitute promising drug targets, of particular
Summary Cortisone was administered to 40 of a total of 60 rats, starting on the day when all animals were infected with Trichinella larvae by stomach tube. Twenty animals were treated for a total of 30 days; the other 20 received cortisone for 60 days. Five months after the primary infections, approximately half of each group of rats was reinfected. Five weeks later, all animals were killed; serum was taken for serologic studies and larval counts were made to determine the numbers of larvae encysted in the musculature. Animals treated for 30 days with cortisone developed slightly greater numbers of encysted larvae than their untreated controls; those treated for 60 days were found to contain very much larger numbers of larvae in the muscles. Upon reinfection, the untreated controls failed to develop additional larvae in the musculature, while the animals treated for 30 and 60 days developed large (and approximately equal) numbers of larvae. Serologic studies, using lyophilized larvae as the source of
