The repair of striated muscle after acute trauma occurs simultaneously by the regeneration of disrupted muscle and formation of connective scar. But, there had been no attention concerning effects of local anesthetics on the degeneration and regeneration process of the injured muscle. The author induced a constant contusion injury on the calf of rats. Lidocaine and/or epinephrine was intramuscularly injected at the site of injury. Morphological and histochemical observation was conducted and the results were as follows: 1. Traumatized striated muscle showed evidences of the healing process for upto 90 days. 2. Morphological and histochemical changes in the traumatized muscle became more severe after the injection of lidocaine and/or epinephrine. 3. Formation of collagenous scar tissue significantly increased after injection of lidocaine and/or epinephrine. Injection of lidocaine or epinephrine developed similar amount of scar after 15 days. 4. Cross section area of the regenerated muscle fibers decreased in the injection groups than in the control groups. Atrophy was significant on day 90 in all types of fiber after injection of the mixture of lidocaine and epinephrine, and in type B after injection of epinephrine. In conclusion, injection of the lidocaine and epinephrine inhibited regeneration of the traumatized striated muscle. Mixture of the drugs showed more inhibitory effect than a single drug.

A household survey was conducted to compare the patterns of morbidity and medical care utilization between medical aid beneficiaries and medical insurance beneficiaries. The study population included 285 medical aid beneficiaries that were completely surveyed and 386 medical insurance beneficiaries selected by simple random sampling from a Dong (Township) in Taegu. Well-trained surveyors mainly interviewed housewives with a structured questionnaire. The morbidity rates of acute illness during the 15-day period, were 63 per 1,000 medical aid beneficiaries and 62 per 1,000 medical insurance beneficiaries. The rates for chronic illness were 123 per 1,000 medical beneficiaries and 73 per 1,000 medical insurance beneficiaries. The most common type of acute illness in medical aid and medical insurance beneficiaries was respiratory disease in medical aid beneficiaries, musculoskeletal disease was most common, but in medical insurance beneficiaries, gastrointestinal disease was most common. The mean duration of acute illness of medical aid beneficiaries was 3.8 days and that of medical insurance beneficiaries was 6.8 days. During the one year period, mean duration of medical aid beneficiaries chronic illnesses was 11.5 months which was almost twice as long compared to medical insurance beneficiaries. Pharmacy was most preferable facility among the acute illness patient in medical aid beneficiaries, but acute cases of medical insurance beneficiaries visited the clinic most commonly. Chronic cases of both groups visited the clinic most frequently. There were some findings suggesting that much unmet need existed among the medical aid beneficiaries. In acute cases, the average number of days of medical aid users utilized medical facilities was less than medical insurance users. On the other hand, the length of medical care utilization of chronic cases was reversed. Geographical accessibility was the most important factors in utilization of medical facilities. Almost half of the study population answered the questions about source of funds on medical security correctly. Most respondents considered that the objective of medical security was affordability. The chief complaint on hospital utilization was the complicated administrative procedures. These findings suggest that there were some problems in the medical aid system, especially in the referral system.
