Changes in roller skiing economy among Nordic combined athletes leading up to the competition season.

The purpose of this study was to compare roller skiing economy during different training phases in Nordic combined (NC) athletes and determine the aerobic and anaerobic factors responsible for changes in skiing economy. Seven elite NC athletes underwent incremental load tests on a large buried treadmill in both spring and autumn using roller skis. Measurements included oxygen uptake, respiratory exchange ratio, and blood lactate concentration.

A case of stricture-type ischemic colitis from excessive alcohol consumption, with follow-up to rule out colon cancer.

A 69-year-old man was admitted to Hanawa Kousei Hospital with acute hepatitis attributed to alcohol consumption. His condition improved with conservative treatment. Computed tomography (CT) showed localized thickening of the colonic wall at the splenic flexure;carcinoembryonic antigen level was slightly elevated to 9.

Assessment of middle-distance running performance in sub-elite young runners using energy cost of running.

The purpose of this study was to assess the validity of v(amax) as an indicator of middle-distance running performance in sub-elite young runners, v(amax) being defined as the quotient maximal oxygen uptake (VO2max) divided by the net energy cost of running (Cr) on a treadmill at a submaximal running velocity (280 m x min[-1]). The VO2max, ventilatory threshold, v(amax), and Cr were assessed in 39 young male sub-elite runners having only small variations in performance level. The relationship between each variable and running performance (at 1500 m, 3000 m, and 5000 m) was evaluated.

Intraventricular craniopharyngioma: report of two cases and review of the literature.

Two unusual cases of purely intraventricular craniopharyngioma are presented. Both patients complained of headache as a sign of increasing intracranial pressure, but neither other neurological deficits nor hormonal disorders were present. Magnetic resonance images showed a mass lesion located within the third ventricle.

[Experimental study on destruction of the third ventricle floor in the midline:--examination for the trans-third ventricle approach].

Surgery of a basilar bifurcation aneurysm is a very difficult operation in neurosurgery. For the treatment of this lesion, two methods are widely used at present: one is the subtemporal approach developed by Drake and the other is the pterional approach by Yasargil. With either approach, however, the treatment of a basilar bifurcation aneurysm accompanied by megadolichobasilar anomaly is difficult and hazardous due to the necessity for excessive retraction of the brain, nerves and vessels.

[A case of hysterical conversion manifested by pain in face and head].

We report a case of hysterical conversion, which was initially diagnosed as trigeminal neuralgia. The pain in the face and head which the patient complained seemed to be consistent with symptoms of trigeminal neuralgia. But it could not be relieved by repeated peripheral nerve blocks and even by Gasserian blocks.

[A case of prolactinoma associated with craniopharyngioma].

A surgical case of prolactinoma associated with craniopharyngioma is reported. A 47-year-old man was admitted to some neurosurgical clinic on October 12, 1982, because of visual disturbance, general fatigue and impotence. Laboratory study revealed hyperprolactinemia (360 ng/ml) and slight enlargement of sella turcica indicated the pituitary adenoma.

[High position basilar top aneurysm treated via third ventricle].

There are two major approaches to basilar top aneurysm: one is subtemporal by Drake, another is pterional by Yasargil. In either approach, however, it is hazardous and difficult to approach basilar top aneurysm with megadolichobasilar anomaly because strong retraction of brain, nerve and vessel is required. A successful case of ruptured basilar top aneurysm with megadolichobasilar anomaly treated directly through the third ventricle is reported.

Sex-related differences in cadmium-induced lipid peroxidation in the rat.

Male and female rats were dosed once a day for 2 days injection with 1.5 mg of Cd/kg as CdCl2. 24 hr after administration of cadmium, lipid peroxidation determined by estimation of malondialdehyde (MDA) was greatly increased in male rat liver, but was not in female rats.

A diagnostic re-evaluation of electric skin resistance, skin temperature and deeper tenderness in patients with abdominal pain.

Diagnostic re-evaluation of measurement of electric skin resistance (ESR), skin temperature (ST) and deeper tenderness (DT) was performed in patients with abdominal pain due to pancreatitis, cholecystopathy and duodenal ulcer. These determinations were conducted when the pain was complained of and after the pain ceased by paravertebral anesthesia. ESR was decreased on the opposite tender points of the abdominal walls as compared with those values of the healthy abdominal walls.
