The effect of liver extract administered to 22 patients after urological operations was evaluated with reference to 19 controls. No significant difference was observed between the cases and the controls. We rather supposed, however, that the liver extract was effective as a liver protection drug, because the results of liver function in the cases were less changed than the controls throughout the post-operative course.
We developed the technique of microexplosion for the destruction of bladder stones and have used it since 1981 with good results. The procedure is safe and simple. A renal pelvic stone in a seventy-one-year-old woman was successfully destroyed by microexplosion using a percutaneous approach. We believe this is the first clinical report on the use of microexplosion for upper urinary tract calculi.
An original electric drill nephroscope was developed for percutaneous nephroureterolithotomy (PNL). In 8 cases large pelvic calculi over 1 cm in diameter were successfully disintegrated and removed.

A study of HLA-D clusters associated with DR4 was performed in the Japanese population. These clusters consist of DYT, DKT2, DB3, and Dw4. Forty-two Japanese typed as DR4 were investigated, and it was found that 17 (40.5%) were DYT, 7 (16.7%) DKT2, 7 (16.7%) DB3, and 4 (9.5%) Dw4.

1. Studies were done on the effects of giving calves two types of concentrate diet, both in a liquid form from an open pail or in a dry pelleted form, on the closure of oesophageal groove, body-weight gains and the digestibility of rations. 2. Twenty-four Holstein calves were used in an experiment by dividing into two groups of twelve calves each. The 'dry-fed' group (DFG) was given a pelleted concentrate, F1, from 25 to 42 d of age, and then given another type of pelleted concentrate, F2, from 43 to 87 d of age, and again given F1 from 88 to 112 d of age. The 'liquid-fed' group (LFG) was given from a pail a liquid suspension of the equivalent amount of the same concentrates as those fed to DFG calves, for the same periods. F1 contained skim milk and glucose with lower levels of maize and soya-bean meal than F2 which did not contain skim milk or glucose; F1 and F2 were both supplemented with 10 g methionine/kg and also supplemented with lysine at 5 and 10 g/kg respectively. All calves were allowed free access to roughage, and digestibilities were measured at 12 and 16 weeks of age. 3. Wet weights of reticulo-rumen and abomasal tissues (% whole stomach weight) were respectively 69.8 and 17.6 in DFG, and 59.0 and 26.4 in LFG at 42 d of age; at 87 d of age, the corresponding values were 68.0 and 16.3 in DFG, and 52.8 and 36.6 in LFG, and further, LFG had significantly more developed caecums and large intestines as well as significantly less developed reticulo-rumens and omasums than DFG. 4. Free amino acid patterns in plasma did not vary in DFG, but varied in LFG in response to the change in diet from F1 to F2 and to the difference between diets in lysine supplementation. 5. Feeding F1 in a liquid form and F2 in a dry form significantly improved calf gains. The intake of roughage in DFG exceeded that in LFG especially when F2 was fed. 6. The digestibility of diethyl ether extracts did not vary with feeding procedures, but that of crude protein (nitrogen x 6.25) was significantly higher in DFG independent of the type of diet. Digestibilities of dry matter and N-free extracts were significantly higher in LFG for F1, while higher in DFG for F2. The digestibility of acid-detergent fibre did not differ significantly between groups at 12 weeks of age, but was significantly higher in LFG at 16 weeks of age, suggesting a possible compensatory contribution of the large intestine to the digestion of fibre in LFG. 7. The efficiency of liquid feeding of a concentrate diet to ruminants compared with that of dry feeding is discussed.
Comparisons of air-dried treatments after etching on the micromechanical bonding of the composite to ionomer surface were made and clinical recommendations are provided. This in vitro study was made to evaluate the adhesion of the interface with a composite resin/bonding agent followed by air-drying surface treatment. The most effective surface conditions were found in the drying treatment groups. Non-air-dried (wiped dry with a tissue) surface groups were less effective.
