Study on the physico-chemical characteristics of breeding grounds in relation to the population density of Anopheles stephensi.

The present study which was based on the quarterly sampling and estimation of various physico-chemical factors throw light on the three significant points with regard to the population build up of Anopheles stephensi. Slightly alkaline pH is essential for higher population density, lower the salinity, higher the population density and higher amount of free ammonia in the water is accounted for the higher population density of A. stephensi.

A note on the effect of different methods of emasculation on gain in body weight in Indian buffalo (Bubalus bubalis) calves.

The effect of Burdizzo, Russian and vasectomy methods of castration on the gain in body weight was studied over a period of 2 1/2 months in the buffalo calves of two age groups (1--1 1/2 years and 2 1/2--3 years). The gain in body weight (1--1 1/2 years age group) has been significantly greater (P less than 0.05) in the control animals (30.3 +/- 3.38 kg) as well as those emasculated by the vasectomy (31.3 +/- 1.4 kg) method in comparison to the other two methods.

Cytologic changes in the pars distalis of male buffalo following emasculation.

The effects of emasculation in the pars distalis of the pituitary gland were studied in male buffalo. Following castration, no size or percentage value changes could be noted in the acidophila and thyrotrophs of the pars distalis. The acidophils were found in greater numbers in the peripheral area of the pars distalis as compared to the central area. However, the frequency of thyrotroph distribution was observed to be more so in the central zone. As for the gonadotrophs, a significant increase in the cell size (P less than 0.05) and percentage value (P less than 0.01) was observed in animals castrated by the Burdizzo method. This points to a state of hyperplasia and hypertrophy of the gonadotrophs as a result of this method of emasculation.
