[Changes in N-acetyl-beta-glucosaminidase (NAG) in prostatitis patients].

NAG was measured before and after treatment and compared in 11 acute prostatitis patients, 13 chronic prostatitis patients and 10 healthy volunteers. Urinary NAG before treatment was 34.1 +/- 18.

Characterization of tubular basement membrane antigens in human kidney.

Tubular basement membrane (TBM) was prepared from normal human kidneys and solubilized with various enzymes. Collagenase digestion released antigenic moieties from the TBM. All four anti-TBM antibodies we studied, three from patients with idiopathic tubulo-interstitial nephritis (TIN) and one from a renal allograft recipient, distinctively reacted with collagenase-digested (CD) TBM during enzyme-linked immunoassay and could discriminate among sera of normal controls or of other nephritis patients, including anti-glomerular basement membrane (anti-GBM) nephritis.

A prediction equation for indirect assessment of anaerobic threshold in male distance runners.

The predictability of anaerobic threshold (AT) from maximal aerobic power, distance running performance, chronological age, and total running distance achieved on the treadmill (TRD) was investigated in a sample of 53 male distance runners, 17-23 years of age. The dependent variable was oxygen uptake (Vo2) at which AT was detected (i.e.

[Urinary tract infection : clinical significance of antibody-coated bacteria].

More attention should be directed to upper urinary tract infections as they cause renal parenchymal damage. Recently, many reports on antibody-coated bacteria (ACB) in urological diseases have been made. We performed ACB tests in 68 cases of urological infectious diseases.

[A case of iodide myxedema observed for 3 years under a low iodide diet--especially on the restoration of the mechanism of escape from the Wolff-Chaikoff effect].

A 47-year-old housewife was admitted to our hospital because of general fatigue and constipation suggesting hypothyroidism. For 3 years before admission, general fatigue, arrhythmia, dry skin, drowsiness, cold intolerance and hypermenorrhea occurred insidiously. She had habitually taken considerable amounts of seaweed every day, e.

[Statistic study of 1,272 cases of foreign bodies in the bladder or urethra].

The foreign bodies in the bladder or urethra found in the clinical observation of the 41 cases treated between April, 1963 and October, 1982, in our Department and those of 1,231 cases so far reported in Japan, were studied statistically. The incidence was higher in males than in females, the ratio being 1.7:1.

[Histopathological studies on bladder carcinoma. 2: Role of local lymph follicle and immunoblast cells].

The relationship between the cellular stromal reaction and systemic immunity was examined in 34 cases of bladder tumors. To determine the cellular stromal reaction, we examined the local lymph follicles such as peritumoral lymphocyte accumulation, and the immunoblast cells having abundant, basophilic cytoplasm with large vesicular nuclei which contained 1-3 large and irregular nucleoli. To measure systemic immunity, lymphocytes, T cells, B cells, IgG-Fc receptor T cells, and lymphocyte blast formation ratio with PHA were examined.

Urinary fibrinogen and fibrin fragments in children with renal disease.

Fibrinogen fragments (X, Y, D and E) and fibrin fragments (D-dimer and E) were examined in the urine of 52 patients with various types of renal diseases. One or more of the fibrinogen fragments were detectable in all the urine specimens. D-Dimer together with fibrinogen fragments was found in 38 of the 52 patients.

[Measurements of cell adhesion to biomaterials by supersonics (author's transl)].

In order to examine eligibility of supersonic vibration energy for investigating cell-material contract, L-strain fibroblasts were cultivated on glass surface and exposed to supersonic vibration. The cells adhered to the glass surface were detached by supersonic vibration and both of adhered cells to the glass surface and detached cells after the supersonic exposure were cultivated for one week. And the cell activity of the detached cells was estimated with cell multiplication by cell nuclei counting and their morphological changes.
