Hypertonic saline solution: an effective wound dressing solution.

In search of a cheaper and effective dressing solution for ulcers, 53 patients presenting with various types of ulcers at the University of Port Harcourt Teaching Hospital were treated with different strengths hypertonic saline 0.3, 0.9, 1.2, 1.5, 2 and 3 osmoles. The ages of the ulcers were between 3 months and 3 years. Optimal results were obtained with solution of 1.5 mmols and above. Desloughing occurred within 2 weeks and granulation was fast and good enough for skin grafting where necessary. Healing was faster in other ulcers that were not due for grafting.

Effects of differential ewe condition at mating and early postmating nutrition on embryo survival.

Ewes in two trials were given either a high (H) or a low (L) level of premating nutrition for 19 wk followed by 6 wk of either H or L postmating nutrition to examine effects on reproductive performance. Trial 1 ewes were 5- to 8-yr-old Polypays and Trial 2 ewes were 3-yr-old Polypay and Coopworth x Polypay crosses. Ewes given L nutrition premating were either immunized with androstenedione-7-carboxyethylthioether:human serum albumin (also known as ovandrotone or Fecundin) in (diethylamino)ethyl-dextran adjuvant (Trial 1) or flushed for 3 wk premating (Trials 1 and 2) to enhance ovulation rates. All ewes were synchronized for mating in both trials. Trial 1 premating treatments created a difference of 10 kg in BW and 1.1 in condition score units between H and L ewes preflushing; flushing halved the BW difference. Ovulation rates averaged 2.58 and were similar for H, L-flushed, and L-immunized (LI) ewes; however, both conception rate and litter size were lowest for immunized ewes. Among both twin and triple-ovulating ewes, highest mean litter size was produced by H ewes, followed in order by L and LI ewes. High postmating nutrition increased BW by 6 kg vs slight weight loss in L ewes, but postmating treatments did not affect litter size of either twin or triple ovulators. The H and L premating groups of Trial 2 differed by 18 kg and 2.2 condition score units preflushing. The H ewes exhibited higher ovulation rates (overall mean = 2.63) but lower conception than the L ewes to synchronized estrus. Litter size averaged 2.15 for H ewes vs 1.82 for L ewes. Among both twin and triple ovulators, L ewes produced fewer lambs than H ewes.(ABSTRACT TRUNCATED AT 250 WORDS)
