The cause of selective degeneration motor neurons in the ventral horn spinal cord associated with amyotrophic lateral sclerosis (ALS) has still not been elucidated. Recently, so-called oxidative stress suggested to be a significant factor pathogenesis this disease. We measured antioxidant actions superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and cytochrome c oxidase (CO) human patients ALS comparison those control patients. Total SOD activity transections from sporadic was...

Abstract —A technique for separating neuronal and glial cell fractions in bulk from rat brain has been developed which does not use any digestive enzymes. Carbonic anhydrase, S‐100 protein 2′,3′‐cyclic nucleotide 3′‐phosphohydrolase were associated with the fraction. Glutamate aspartate most abundant free amino acids; fraction was richer GABA glycine than Both d ‐glutamate potassium ions actively accumulated each during aerobic incubation. Na,K‐ATPase higher fraction; its activity,...

Mesenteric phlebosclerosis (MP) is a disease characterized by fibrotic change or calcification of the mesenteric vein. Recently, there has been an increase in case reports MP related to herbal medicine usage. Long-term intake gardenia fruit (GF) suspected as possible cause. However, many GF users do not develop this and association between remains unclear. In study, we investigated for first time dosage used patients with without MP. We medical chart review study design assess reviewed...

Abstract: The time courses of changes three enolase isozymes (αα, αγ, and γγ), S‐100 protein, 2′,3′‐cyclic nucleotide 3′‐phosphodiesterase (CNPase), ornithine decarboxylase (ODC), β‐galactosidase, glucose‐6‐phosphate dehydrogenase (G6PDH) were examined from 1 to 14 days after cutting the preganglionic nerve (denervation) or postganglionic (axotomy) superior cervical sympathetic ganglion (SCG) rat. wet weight protein content in axotomized SCG increased continuously, nearly twice those...

The concentration of naturally synthesized nerve growth factor (NGF) was measured in various tissues adult rats, using a highly sensitive two-site enzyme immunoassay. highest found the superior cervical sympathetic ganglion (SCG). Transection postganglionic external carotid (ECN) reduced ganglionic level NGF more than did section internal (ICN). When both preganglionic and ECN were cut, decreased even more. On other hand, when ICN sectioned, leaving intact, endogenous content SCG...

We evaluated the effect of keishibukuryogan (KBG; Guizhi-Fuling-Wan), a traditional Japanese (Kampo) formula, on endothelial function assessed by reactive hyperemia peripheral arterial tonometry (Endo-PAT2000) in patients with metabolic syndrome-related factors controlled clinical trial crossover design. Ninety-two were assigned to group A (first KBG-treatment period, then control period; each lasting 4 weeks, about one-year interval) or B control, KBG-treatment). In forty-nine (27, A; 22,...

1. [3H]acetylcholine (ACh) or [3H]gamma‐aminobutyric acid (GABA) was injected into the cell body of a cholinergic neurone Aplysia kurodai. 2. [3H]ACh moved down axon at maximum speed 2.5 mm/sec 20 degrees C. 3. mM‐colchicine suppressed this movement, but some passive movement radioactivity noted along axon. 4.

To determine whether the response to progestin challenge test can be predicted from endometrial thickness measured sonographically. Progestin tests were performed on 44 women with secondary amenorrhea, each of whom also had her by transvaginal ultrasonography and serum estradiol (E2) levels determined. The relationships between test, thickness, E2 studied, as well presence or absence withdrawal bleeding could levels. endometrium was significantly thicker in 32 who (10.3 ± 4.1 mm) than 12 did...

Rats fed from weaning on semi-purified diets supplemented either with linoleate-rich safflower oil (S) or alpha-linolenate-rich perilla (P) were mated. Half of the progeny weaned to original diet dams (SS and PP), other two groups shifted enriched in fatty acid (SP PS). Brightness-discrimination learning ability was tested daily for 30 d beginning at 11 weeks age, a bright light as positive stimulus. The performance inferior group through generations (SS) compared (PP) which (PS SP)....

Objective Mesenteric phlebosclerosis (MP) is a disease characterized by calcification of the mesenteric vein, which causes chronic ischemia. Recently, long-term intake gardenia fruit ('Sanshishi' in Japanese) has been attracting attention as possible cause. Usually, only advanced, severe MP cases get reported. However, we suspected that some latent this may exist. We performed study order to determine prediagnostic at our outpatient departments herbal (Kampo) medicine, with particular paid...
