Finger systolic blood pressure measurements after finger cooling. Using the laser-Doppler method for assessing vibration-induced white finger.

Finger systolic blood pressure (FSBP) measurements after finger and body cooling using a strain-gauge plethysmograph is a useful objective test for diagnosing Raynaud's phenomenon (RP). Body cooling, however, is uncomfortable to subjects. In this study, the measurements of FSBP after finger cooling without body cooling, using Digitmatic DM2000 (Medimatic) combined with laser-Doppler flowmetry (ALF2100 Advance), were performed in 99 vibration-exposed men (40 men without RP, 39 men with mild RP, and 20 men with severe RP) and 13 healthy controls. This method is relatively useful for assessing the severity of vibration-induced white finger (VWF).

Experimental induction of uterine cancer in rats by N-ethyl-N'-nitro-N-nitrosoguanidine dissolved in polyethylene glycol.

In the present experiment we attempted to experimentally induce uterine cancer in rats by injecting into the uterine cavity N-ethyl-N'-nitro-N-nitrosoguanidine (ENNG) dissolved in polyethylene glycol (PEG). Fifty-nine female F-344 rats, 7-8 weeks old, were divided into three groups and each received in the left uterine cavity with laparotomy a single dose of ENNG dissolved in PEG according to the following schedule: Group 1 received 75 mg ENNG/kg body wt.; Group 2 had 20 mg ENNG/kg body wt.: and Group 3 was given only PEG. In Group 1 it was observed that adenocarcinoma and sarcoma were present in the uterine corpus while squamous cell carcinoma occurred in the uterine cervix. In Group 2, although tumors such as adenocarcinoma, adenoma and sarcoma were observed in the uterine corpus, no tumor was present in the uterine cervix. No tumor growth whatsoever was observed in Group 3. From the above results it is apparent that the present method is an efficient means for experimentally inducing uterine cancer and that the site of tumor generation varies according to the concentration of ENNG administered.

A day care program and evaluation of animal-assisted therapy (AAT) for the elderly with senile dementia.

We conducted a survey to clarify the evaluation methods of animal-assisted therapy (AAT) for the elderly with senile dementia in an adult day care center. AAT was implemented for a total of six biweekly sessions. The AAT group consisted of seven subjects and the control group numbered 20 subjects. In a comparison between Mini-Mental State Exam (MMSE) scores at baseline and those measured three months later, the average MMSE score before AAT (baseline) was 11.43 (+/- 9.00), and three months later it was 12.29(+/- 9.69). In the AAT group, the average score on Nishimura's Activities of Daily Living (N-ADL) at baseline was 28.43(+/- 14.00), and after ATT it was 29.57(+/- 14.47). In the AAT group, the average baseline score on behavioral pathology of Alzheimer's disease (Behave-AD) was 11.14(+/- 4.85), and three months after AAT it was 7.29(+/- 7.11) (p < 0.05). In the control group, the average baseline score was 5.45(+/- 3.27) and three months later it was 5.63(+/- 3.59). The evaluation of salivary CgA, as a mental stress index, showed a decreasing tendency in the AAT group. Our findings demonstrate the usefulness of using several methods for evaluation of the changes in patients given AAT.
