The present short communication puts on record a case of bilateral, multiple follicular cysts in a water buffalo along with a detailed description of its ovarian biometry and follicular fluid composition. The ovarian weight and biometrical parameters were much higher than in normal cycling buffaloes. A total of three follicular cysts were observed, two on the right ovary and one on the left ovary, measuring 4.9, 3.0 and 2.6 cm yielding 21, 9 and 5 ml of follicular fluid, respectively. The cystic fluid was deep yellow in colour with a viscous consistency. The follicular fluid concentrations of glucose, total protein, cholesterol, acid phosphatase, calcium, phosphorus and progesterone in all the cysts were within the range reported previously in normal buffalo follicular fluid; however, the alkaline phosphatase concentration in cyst 1 and total bilirubin concentration in cysts 1 and 2 were higher than the values in normal follicular fluid. In contrast, the levels of urea nitrogen in cysts 1 and 3, and oestradiol in cyst 3 were lower than the normal values. All the three follicles had an oestradiol to progesterone ratio less than 1. The results of our study suggest that follicular cysts in buffalo are oestrogenically inactive and have an altered concentration of certain biochemical and hormonal constituents.
本简短通讯记录了一例水牛双侧多发性卵泡囊肿病例，并对其卵巢生物测量和卵泡液成分进行了详细描述。该病例的卵巢重量和生物测量参数远高于正常发情周期的水牛。共观察到三个卵泡囊肿，右侧卵巢两个，左侧卵巢一个，大小分别为4.9厘米、3.0厘米和2.6厘米，分别产生21毫升、9毫升和5毫升卵泡液。囊液颜色深黄，质地粘稠。所有囊肿中葡萄糖、总蛋白、胆固醇、酸性磷酸酶、钙、磷和孕酮的卵泡液浓度均在先前报道的正常水牛卵泡液范围内；然而，囊肿1中的碱性磷酸酶浓度以及囊肿1和2中的总胆红素浓度高于正常卵泡液中的值。相比之下，囊肿1和3中的尿素氮水平以及囊肿3中的雌二醇水平低于正常值。所有三个卵泡的雌二醇与孕酮比值均小于1。我们的研究结果表明，水牛卵泡囊肿雌激素活性不足，某些生化和激素成分的浓度发生了改变。
