ABSTRACT
Effects of different nutrient solutions, organic supplements and plant growth regulators on in vitro seed germination and protocorm development of Geodorum densiflorum (Lam.) Schltr. were studied. Seed germination was very high (up to 96%) in all the basal media, with Knudson's C and half-strength Murashige & Skoog being slightly more productive than Vacin & Went. Application of organic supplements and NAA had little effect on germination, but BAP proved inhibitory. After germination, protocorms exhibited a clear preference for peptone and NAA for much faster growth, while BAP resulted in stunted growth. Beside normal development, disorganisation of protocorms, followed by callusing occurred in presence of peptone and NAA. The calli were compact with limited growth and frequently regenerated protocorm like bodies. Development of seedlings was preceded by an intermediary rhizome phase. Growth of rhizomes was slow in the plant growth regulator free medium and about 15 months of culture was required for seedling formation. However, it was possible to hasten the process by 8-10 months with the employment of NAA, which also enhanced the number of seedlings per protocorm through axillary branching. Combined application of high BAP and low NAA was also useful for high rate of seedling formation.

BACKGROUND: We aimed to identify the factors involved in the occurrence of unwanted pregnancy in women seeking medical termination of pregnancy, and to describe their contraceptive practices. METHODS: A descriptive interview-based study of 402 women seeking abortion was done. Information was gathered regarding demographic variables, contraceptive practices and reasons for the unwanted pregnancy. RESULTS: All the women in our sample were married and multiparous. The husband's unwillingness for contraception and the improper use of condoms was responsible for one-third of all unwanted pregnancies. Lactation was believed to be a protection against pregnancy by 11.3% of women while 6.3% were unaware of any contraceptive method. CONCLUSION: We believe that focusing on these areas in public health programmes will help to decrease the number of unwanted pregnancies.

The biological half life, blood level and tissue dispersion of sulfisomidine in poultry have been studied. The biological half life was observed to be 40 minuts. Following single dose (275 mg/kg) oral administration, the peak blood level of 13.92 mg% was found at 2 hr and the liver and small intestine showed highest drug residue at the end of 24 hr.
