JOURNAL FREE ACCESSWe examined and reviewed the association between Parkinson's disease and vitamin B status. Thiamin triphosphate (TIP), but not thiamin, increased dopamine (DA) release from the rat striatum. We concluded that TTP could enhance the Na^+ permeability of the membrane, depolarize nerve cells, and sequentially cause a Ca^<2+> influx, inducing DA release. DOPA administration enhanced the elevation of serum homocysteine level. Hyperhomocysteinemia is considered to be a risk factor of Parkinson's disease as well as vascular diseases and Alzheimer's disease. Folate, vitamin B_<12>, or vitamin B_6 could potentially reduce the level of serum homocysteine. We reported that folate deficiency was not a rare condition in elderly neurological patients in Japan. They showed both peripheral and central nervous system disorders, including dementia. Folate supplementation had beneficial effects for two-thirds of the patients. Although further studies are needed, folate and other vitamins might have an inhibitory effect on the progression of Parkinson's disease.View full abstractDownload PDF (930K) -

JOURNAL FREE ACCESSIn studies of rat coprophagy, feces classification was never successfully undertaken until 1997 when we described two types of feces, usual and hydrous or reingested feces. After identifying feces, those nutritional compositions were compared. Hydrous feces had higher amino acid values than usual feces, although with no specific pattern. Sodium and potassium values were 2.5 times larger in hydrous feces than in usual feces, accounting for only 5% of the feed-derived amount. Vitamin B_<12> and folic acid values in hydrous feces were higher than in usual feces, with vitamin B_<12> values 5 times larger than those of feed-derived sources. Caecectomy failed to prevent coprophagy although it affected vitamin B_<12> and folic acid values. Caecectomized rats grew normally with little increase in feed intake although not enough to support vitamin B_<12> intake. Moreover, cobalt intake also was not enough to support vitamin B_<12> synthesis. Further studies about coprophagy in rats are needed.View full abstractDownload PDF (1018K) -
