Menarche: prior knowledge and experience.

The purpose of this study was to determine the details of first menstruation and the differences between those who had knowledge of menstruation prior to menarche and those who did not. Information from 305 young women in India was collected regarding menarcheal bleeding pattern, disturbances in normal menstruation, and menarcheal age. Those who had knowledge prior to menarche considered it to be a normal physiological function, while those who did not were "appalled" and "horrified." Those having prior knowledge had a high rate of regularity, lower rate of dysmenorrhea, and earlier onset of menarche. The subjects were unanimous in their desire for more information to be provided prior to menarche.

Semen electrolytes in normal and infertile subjects. II. Zinc.

Zinc levels in seminal plasma of normal subjects are compared with those of oligospermic, asthenospermic and azoospermic. A linear direct relationship seems to exist between zinc in seminal plasma and motility of spermatozoans. The possible implications of this are discussed.

Pulmonary function and morbidity in textile mill workers.

The study was conducted in a large cotton textile mill in Surat City. A selected number of 278 employees were evaluated for social, anthropological and pulmonary functions. No parameters except the period of exposure to dust reduced pulmonary function; it was statistically significant in the case of vital capacity and maximum breathing capacity. Out of 23.94% pulmonary morbidity observed, the byssinosis rate was 1.62.

Seminal plasma fructose and glucose in normal and pathological conditions.

A total number of ninety four semen samples were analysed which included normozoospermia (39), oligozoospermia (6), oligoasthenozoospermia (10), asthenozoospermia (15) and azoospermia (24). A positive correlation (r = 0.344) was existing between sperm count and motility in normozoospermia. Seminal plasma was estimated for fructose (94) and glucose (73). It was found that there was a statistical difference between the values of oligozoospermia and all other groups studied for fructose. A strong positive correlation (r = 0.394) was existing between percentage of motility of spermatozoa and fructose in normozoospermia showing that fructose is very essential for increased number of motile spermatozoa. Likewise a relationship (r = 0.451) was seen between sperm count and glucose in normal. This gives an impression that both these are regulated by one source.

Sodium and potassium in normal and pathological seminal plasma.

A total number of 273 seminal plasma samples from normozoospermia (n = 91), oligozoospermia (n. = 50), oligoasthenozoospermia (n = 76), asthenozoospermia (n = 10) and azoospermia (n = 46) were analysed for sodium and potassium. A decreased sodium level was seen in pathological groups. A negative correlation was found to be in existence between sodium and potassium in seminal plasma in the groups studied except in azoospermia. Positive correlation was found between sodium and motile spermatozoa in normal and oligozoospermia. In oligoasthenozoospermia it was negative. Potassium was negatively correlated with percentage of motile spermatozoa in the groups studied.
