Reproductive Effect

Terbinafine is a fungicide given orally with the dose of 100 mg/kg body weight per day for each ewe for 60 days. The vaginal smears of ewe, body and ovarian weight were daily administered at slaughter time; ewes were slaughtered at 60th day. Estrous cycle was affected by showing a significant reduce in the estrous cycle length of each phases of estrous cycle with associated significant increase in the diestrus phase in terbinafine treatment as compared with control group (olive oil treatment as adjuvant) of ewes. There was a significant reduce in the number of follicles and a significant raise in the number of atretic follicles in treated group as compared with control group as well as upsurge the progesterone/estrogen ratio. The body and ovarian weight were significant diminished in terbinafine treatment. These observed effects of terbinafine on the ovarian activity may be due to a direct effect as antiproliferative agent or the hypothalamus - hypophysial - ovarian axis causing hormonal inequality.

No experimento foram utilizados 62 animais da raça Charolesa e Caracú, inseminados artificialmente (IA). No 7o dia após a IA, as vacas foram divididas aleatoriamente em 2 grupos: tratado (n=32), que recebeu 2.500 UI de hCG (IM) e controle (n=30), que recebeu 1 ml de solução fisiológica estéril, (IM). O diagnóstico de prenhez foi realizado por toque retal no 45o dia após a IA. Resultados: A duração do ciclo estral diferiu (P0,05) entre o grupo tratado e controle (40,62% e 23,33%, respectivamente). Conclusões: A duração do ciclo estral dos animais tratados foi prolongada em relação aos controles (P0,05) as taxas de prenhez em bovinos de corte. Effect of human chorionic gonadotropin (hCG) on estrous cycle length and pregnancy rates in cattle Abstract In the present experiment a total of 62 cows of Charoles and Caracú breeds, artificially inseminated (AI). At day 7th after AI the cows were aleatory distributed in two groups: treated group (n=32) that receive 2.500 UI of human chorionic gonadotropin (hCG) by the intramuscular route and control group (n=30) to wich 1.0 ml of sterile physiological solution was administered also by the intramuscular route. It has been found that the estrous cycle lenght was different (P0,05) between treated and the control groups (40,6 and 23,3%, respectively). In this way, the estrous cycle lenght of the treated cows was extended in regard to the control cows. The hCG administration did not increase pregnant rates.

This study was designed to examine the effect of the intrauterine infusion of platelet-rich plasma (PRP) or equine lyophilized growth factor (L-GFequina) on the follicular growth, endometrial thickness, estrus cycle length, and pregnancy rate in purebred Arabian mares. A total of 73 purebred Arabian mares who experienced repeat breeding for three successive cycles were randomly divided into the following three groups: control group, without treatment; second Group (PRP group), in which mares were intrauterine infused with 20 mL of fresh PRP on the second day after the end of physic estrus phase; and the third group (L-GFequina Group), consisting of mares that were intrauterine infused with 20 mL of reconstituted lyophilized horse platelets growth factors (L-GFequina) on the second day after the estrus phase. The results showed no significant difference between control and treated groups in the diameter of the preovulatory follicles during the post treatment cycle. The endometrium thickness increased significantly in the L-GFequina and PRP groups ahead of the non-treated group. Intrauterine L-GFequina or PRP administration shortened the estrus cycle length. A higher pregnancy rate was recorded in the L-GFequina and PRP treated mares. In conclusion, the intrauterine infusion of L-GFequina or PRP increased the endometrial thickness and pregnancy rate and could be used to improve fertility in Arabian purebred mares who experienced from repeat breeding.

Estrus Detection

Forty non-lactating, cyclic adult Pelibuey ewes were randomly divided into six groups. Estrus was synchronized within each group using intravaginal sponges and prostaglandin F2&alpha; injection at the time of the sponge removal. The sponges were inserted and removed on different dates in each group, but all the groups except the control one were first exposed to rams on the same date (July 17<sup>th</sup>), so that at the time of the first exposure the ewes were either on day 0 (group D0; n = 7), 3 (group D3; n = 7), 8 (group D8; n = 7), 12 (group D12; n = 7) or 14 (group D14; n = 7) of their synchronized estrous cycle. Thereafter the ewes of these groups remained continuously exposed to the males until all the females showed estrus. The ewes in the control group (CG; n = 5) remained isolated from all the males, except for 5-minute periods at the time of estrus detection, which was carried out three times a day. Progesterone concentrations were determined in plasma samples taken daily from two days before the initial exposure to the males until the onset of the next estrus. There were no differences in estrous cycle length between the groups exposed to rams and the control group (P &gt; 0.05). The interval from the assumed onset of the estrous cycle (48 h after sponge removal) until the occurrence of luteolysis was not different between the control group and any of the groups exposed to the males. The interval from luteolysis to estrus was not modified by exposure to the males (P &gt; 0.05). Estrus duration was shorter (P &lt; 0.06) in the control group than in group D3. It is concluded that the exposure of cyclic Pelibuey ewes to males does not advance the time of luteolysis and does not affect the length of the estrous cycle. Therefore, the male effect does not synchronize the next estrus of cyclic Pelibuey ewes. &nbsp;

Background: Ovulation induction with clomiphene citrate in women with infertility has been practiced more than 40% years but in infertile patients this treatment plan proved to be ineffective with multiple complication. Body weight plays an important role modulating reproductive development and functioning. Aim: To observe the effects on body weight of female albino rat after use of clomiphene citrate and letrozole for consecutive 1-4 estrous cycles Method: Eighty four adult female Albino rats were equally divided into three groups for this research. Body weight of each rat was measured before and after the experiment. Vaginal smear cytology of each rat was performed to study different phases of estrous cycle. Control group A was given normal saline orally , In Experimental group B rats were given letrozole (Femara) at dose 5mg/kg orally and in Experimental group C rats were given clomiphene citrate at dose 100ug/kg orally. Results: Significant weight gain is observed in rats taking clomiphene citrate as compared to letrozole Conclusion : Comiphene citrate directly affects the body weight which indirectly reduces the ovulation induction and pregnancy rate. Letrozole is good alternate for ovulation induction and for CC resistant patients. Keywords: Estrous cycle, body weight, citrate and letrozole

Abstract The biomechanical and biochemical properties of aortas from female rats treated with biosynthetic human GH (b-hGH) for 80 days were investigated. b-hGH was administered at a dose of 5 mg·kg−1·d−1. Treatment with b-hGH increased the body weight by 75% and the diameter of the aorta by 14% compared with the control group. The concentration of collagen and the relative amount of collagen type I were increased, and the concentration of elastin was decreased. Aortas from the b-hGH-treated group showed increased extensibility in the regions corresponding to physiological load values (i.e. 100-200 mmHg), and increased stiffness in regions with higher load values. The increased extensibility at low load values corresponds well with the loss of elastin, and the increased stiffness at higher load values with the increase of collagen and relative increase of collagen type I. These alterations induced by the growth hormone treatment might influence the elasticity and recoiling properties of the aorta.

Study Results

The anti-diabetic effect of ethanolic and aqueous extracts of Imperata cylindrical  rhizomes was investigated in alloxan-induced diabeties in rats. Diabetes was induced by a single 150 mg/kg intraperitoneal dose of alloxan. Rats were divided into five groups with six rats in each group i.e. the normal control group, diabetic control group, standard group (glibenclamide, 10mg/kg, p.o.), Test-I group (200 mg/kg ethanolic extract) and Test-II group (200 mg/kg aqueous extract). The above concerned groups were inoculated on 21st day. On the last day of the experiment, fasted rats were killed by cervical dislocation. The body weight was measured at the initial day and final day. The blood samples were collected for estimation of glucose. The loss of body weight in control group, but recovery was observed in drug treated group. The serum glucose level was significant increased in diabetic rats. However, significant improvement was observed in treated group. The biochemical parameters such as HDL and proteins level were decreased in the control group but maintained in drug treated group. LDL, cholesterol, triglyceride creatinine and urea were significant increase in control group however, reduced level in drug treated group. The present study concluded that ethanolic and aqueous extracts of I. cylindrical  rhizome showed an appreciable effect in reducing the hyperglycemia and the complications associated with diabetes. However, aqueous extract is found more significant in decreasing blood glucose level in comparison to the ethanolic extract. The study results justify the traditional use of the plant as anti-diabetic.

Aim of the Study: This study was undertaken to ascertain if Hibiscus sabdariffa extract can affect the lipid profile (Total cholesterol (TC), triglycerides (TG), high density lipoprotein (HDL), very low density lipoprotein (VLDL), and low density lipoprotein (LDL)) levels in a paracetamol- induced hepatotoxicity using albino Wistar rat as a model. Materials and Methods: Thirty (30) rats used for this study were divided into three groups. Group A (n=10) served as control. Group B (n=10) was administered paracetamol only at a dose of 750 mg/kg body weight. Group C (n=10) was administered paracetamol (dose 750 mg/kg body weight) and aqueous extract of H. sabdariffa (dose 10 ml/kg body weight) of the animal for 3 weeks. All animals were allowed free access to clean drinking water and normal rat chow. Results: Results of the study revealed that TC was significantly lower (p<0.05) in the paracetamol + H. sabdariffa-treated group as compared to paracetamol-treated group and control respectively. Similar trend was observed with TG, VLDL-c, LDL-c and HDL-c. However, the decrease in HDL-c was not statistically significant when compared to control. Conclusion: The presence of bioactive constituents vis; anthocyanins, flavonoids, polyvenols and free radical scavenging properties in H. sabdariffa enabled a hypolipidemic effect on the animals by lowering the levels of serum TG, VLDL-c, LDL-c despite challenge on the liver. However, it was unable to produce significant effect on HDL concentration -very important cholesterol required in high level to maintain homeostasis inside the body. This may be due to the challenge on the liver as a result of the paracetamol abuse.

Cadmium (Cd) present in the air, drinking water and food has the potential to affect the health of people, mainly those who live in highly industrialized regions. Cd affects placental function, may cross the placental barrier and directly modify fetal development. It is also excreted into milk. The body is particularly susceptible to Cd exposure during perinatal period. The effect on rat oral epithelium (floor of the mouth) after continuous exposure to drinking water containing low levels of Cd during lactation was studied. Female rats were supplied with ad libitum drinking water containing 300 mg/l of CdCl2 throughout the whole lactation period. Control animals received a similar volume of water without Cd. Lactating rats (21 day-old) were killed by lethal dose of anesthetic. The heads were retrieved, fixed in "alfac" solution (alcohol, acetic acid and formaldehyde) for 24 h, serially sectioned in frontal plane, at the level of the first molars. The 6 µm sections were then stained with hematoxylin and eosin. Nuclear epithelium parameters were estimated, as well as cytoplasm and cell volume, nucleus/cytoplasm ratio, numeric and surface densities, and epithelial thickness. Mean body weight was 34.86 g for the control group and 18.56 g for the Cd-treated group. Histologically, the floor of the mouth epithelium was thinner in the treated group, with smaller and more numerous cells. In this experiment, Cd induced epithelial hypotrophy, indicating a direct action in oral mucosa cells, besides retarded development of the pups.

Abstract Sixty patients with intermittent claudication participated in a double-blind placebo-controlled trial of 20 courses of intravenous chelation therapy with 3 g of disodium EDTA vs placebo during 5-9 weeks. After the first infusion, the 24-h urinary excretion of lead and zinc was approximately 25-fold higher in the EDTA-treated group; relative differences for copper and calcium were smaller. Urinary magnesium excretion in the EDTA-treated group was one-third less than in the control group. After the treatment period, the blood lead concentration had decreased by approximately 73% and the serum zinc concentration by approximately 34%; other changes in blood concentrations were negligible. The loss of essential minerals and the possible redistribution of lead in the body may constitute a disadvantage that should be taken into account in repeated intravenous EDTA treatment.
