Aim:The aim of this study was to investigate the effect of kisspeptin (KP) on in vitro maturation (IVM) of sheep oocytes aspirated from the ovaries collected from slaughterhouse.Materials and Methods:Two different experiments were conducted to investigate the effect of KP (5, 10 and 15 µg/ml) alone (experiment 1) or in combination with follicle-stimulating hormone (FSH), luteinizing hormone (LH), and Estradiol (E2) (experiment 2) on IVM of sheep oocytes. Tissue culture medium 199 supplemented with Gentamicin was used as control medium. Good quality oocytes were randomly allocated into different IVM media and cultured at 38.5°C in 5% CO2 under humidified atmosphere for 24 h. The oocytes were evaluated for their cumulus cell expansion (CCE) and extrusion of the 1st polar body (PB) at the end of maturation.Results:The proportion of oocytes showing CCE and extrusion of PB was highest when the oocytes were matured in the medium supplemented with 10 µg/ml of KP. In experiment 2, oocytes were matured in 12 different maturation media (G1-G12: G1: Control, G2: KP alone, G3: FSH, G4: FSH+KP, G5: LH, G6: LH+KP, G7: E2, G8: E2+KP, G9: FSH+LH+E2, G10: FSH+LH+E2+KP, G11: FSH+LH+E2+fetal bovine serum (FBS), G12: FSH+LH+E2+FBS+KP). The proportion of oocytes showing cumulus expansion and PB extrusion was highest (98.33±1.05 and 89.17±2.38) when they were matured in FSH+LH+E2+FBS+KP (G12) and was significantly higher than other groups. The proportion of CCE and extrusion of PB was significantly increased when KP was supplemented to FSH and E2, but no effect was observed with LH. The maturation rates were significantly increased when FSH, LH, and E2 (G9) containing media were additionally supplemented with KP (G10).Conclusion:This study demonstrated that the addition of KP (10 µg/ml) to the FSH, LH, and E2 supplemented media would enhance the sheep oocyte maturation in vitro.

This study was undertaken on canine pyometra and consisted of 28 bitches of different breeds with known breeding history and open type of pyometra. The diagnosis of pyometra was made by correlating the history and clinical signs with the findings of abdominal palpation, radiography and ultrasonography. The physiological, haematological and biochemical parameters were evaluated before and at the end of therapy. The clinical cases were divided randomly into four different groups with each group consisting of seven bitches. One untreated control group in which bitches were given only supportive therapies was included. The bitches in the other three groups were treated using natural PGF 2 α or synthetic PGF 2 α or a combination of a dopamine agonist prolactininhibiting drug, i.e., cabergoline and lower dose of synthetic PGF 2 α (Cloprostenol) along with supportive therapies. Treatment of canine pyometra by the use of different drugs was found to be successful. Though a lower dose of cloprostenol was effective in treating pyometra, it is not recommended due to high rates of recurrence and lower conception rates. Treatment of canine pyometra using a combination of a dopamine agonist prolactin-inhibiting drug (Cabergoline) and a lower dose of synthetic PGF 2 α (Cloprostenol) was found to be the most effective method among the three therapeutic protocols used in the present study.

Aim:The aim of the study was to find out alteration in physiological and haematological parameters in bitches affected with pyometra. Materials and methods:Physiological and haematological parameters were studied in twenty eight bitches affected with pyometra.Results: Evaluation of physiological parameters revealed that rectal temperature and respiration rate were increased in the bitches affected with pyometra where as heart rate did not reveal any significant change. In haematological parameters, haemoglobin, packed cell volume (PCV), total erythrocyte count (TEC) and lymphocyte count were decreased in the bitches affected with pyometra. The total leucocyte count (TLC), neutrophil count and monocyte count were increased in pyometra. Erythrocytic indices like mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) did not show any significant changes in the bitches. Conclusion:Normocytic and normochromic anaemia, leucocytosis, a predominant absolute neutrophilia, lymphopenia and monocytosis were the most common findings in all the bitches affected with pyometra.
