Effects of nutritional conditions around weaning on carbonic anhydrase activity in the parotid gland and ruminal and abomasal epithelia of Holstein calves.

Thirty-two male Holstein calves were used to investigate the effects of nutritional conditions around weaning and aging on carbonic anhydrase (CA) activity in the parotid gland and epithelium from the rumen and abomasum. We fed calf starter and lucerne hay as well as milk replacer (group N) or fed milk replacer either with (group S) or without (group M) administration of short-chain fatty acids (SCFA) through polypropylene tubing into the forestomach until 13 weeks of age. The diets were fed at 1000 hours and 1600 hours, and SCFA were administrated after milk replacer feeding at 1600 hours.

Routed protein migration after protein extravasation and water leakage caused by cold injury.

The movement of extravasated endogenous protein induced by cold injury was investigated in the rat. Extravasated proteins were observed around the cold injury immediately after injury; within 3 hr they had moved into the ipsi- and contralateral hemispheres along the nerve fibres (routed protein migration). The water content in the areas where the extravasated protein was observed was increased, and NMR-CT scans (TR 2000 msec, TE 90 msec) showed high intensity patterns whose distribution and progression coincided with those of extravasated protein.

[Metabolic acidosis and hypoglycemia during calcium hopantenate administration--report on 5 patients].

Calcium hopantenate (HOPA) has been widely used as an activator of cerebral metabolism in Japan. However, several cases of acute encephalopathy during HOPA administration were recently reported, which were characterized by marked metabolic acidosis and hypoglycemia. The encephalopathy in these patients was named Reye-like syndrome because of the similarity to Reye's syndrome in children.
