Developmental surface ultrastructure of Macroorchis spinulosus was studied by scanning electron microscopy. One-day-old juvenile fluke was leaf-shaped and bent ventrally. Body surface was covered densely with peg-like spines and with cobblestone-like cytoplasmic processes. Ciliated sensory papillae were concentrated around oral sucker. Several unciliated sensory papillae occurred equidistantly on oral sucker and acetabulum. The ciliated papillae appeared in two longitudinal lines symmetric bilaterally on dorsal surface. On adult flukes, tegumantal spines became wider in middle of the body surface. The cytoplasmic processes differentiated into more fine velvety form. It is likely that the differentiated fine cytoplasmic processes are an increased absorptive surface to adult M. spinulosus. It is suggested that single pointed tegumental spines on anterior half of the body may be supportive for this fluke to migration.

Scrub typhus (Tsutsugamushi disease)is an acute febrile systemic illness caused by Rickettsia tsutsugamushi that is transmitted to humans by the bite of larval-stage trombiculid mites (chiggers). The authors analyzed chest radiographic findings of scrub typhus in 160 patients in Ulsan area. One hundred and eight (67.5%) of160 patients showed abnormal findings which included lung lesions in 108 patients (67.5%), cardiomegaly in 37 patients (23.1%), lymphadenopathy in 25 patients (15.6%) and pleural effusion in 11 patients (6.9%). Among the lung lesions, interstitial patterns were seen in 107 patients (66.9%), mostly fine or medium reticulonodular, and air-space patterns in 14 patients(8.8%) and combined interstitial and air-space patterns in 13 patients (8.1%). Sixty-four patients(40%) had combined chest radiographic findings. The typical chest radiographic findings of scrub typhus would be helpful in evaluation of the causes of acute febrile illness that occur during late fall in the endemic area.

BACKGROUND: Cyclosporine, an immune suppressive agent has been reported to potentiate the neuromuscular blockade induced by vecuronium and atracurium. And the potentiation degree was more prominent in the vecuronium. Rocuronium and mivacurium have been introduced into clinical practice recently and there is no report whether the cyclosporine potentiates the neuromuscular blocking effects of these agents. We, therefore studied the effect of Sandimun (cyclosporine in cremophor-ethanol) on the neuromuscular blockade action of rocuronium and mivacurium in rabbits. METHOD: The effect of Sandimun on the rocuronium and mivacurium were investigated in anesthetized 30 rabbits. The rabbits were divided into five groups; rocuronium group (rocuronium bromide 1 mg/kg iv), rocuronium - Sandimun group (rocuronium bromide 0.1 mg/kg iv after Sandimun 5 mg/kg iv), mivacurium group (mivacurium chloride 0.064 mg/kg iv), mivacurium - Sandimun group (mivacurium chloride 0.064 mg/kg iv after Sandimun 5 mg/kg iv) and Sandimun group (Sandimun 5 mg/kg iv). Neuromuscular block was assessed by measuring the response of anterior tibial muscle to 0.1Hz single twitch stimulation of the common peroneal nerve. Onset time, duration of muscle relaxation and recovery index were compared among the groups. RESULTS: There were no significant differences in onset time and recovery indices among the groups. Significant difference was found in duration between the rocuronium group and the rocuronium-Sandimun group (p<0.05). CONCLUSION: Sandimun potentiates the rocuronium - induced neuromuscular blockade but not the neuromuscular blocking action of mivacurium.

Polyarteritis nodosa is one of the necrotizing vasculitis inv'olving small and medium sized arteries. Polyarteritis nodosa may affect many organs such as kidney, musculoskeletal system, gastrointestinal tract, skin, heart, and nerve. In Cupps and Fauci's autopsy studies, muscle involvement was found in 39% of the patients with polyarteritis nodosa. Commonly Polyarteritis nodosa may be presented clinically by myalgia. We experienced a case of polyarteritis nodosa presenting as myositis, diagnosed by muscle biopsy and renal angiography, which appear with unusual presentation of joint contracture in lt elbow and muscle crarnping pain rather than cornmonly presented myalgla.

The radiologic findings of lumbosacral spine and measurement of lumbosacral angle were analysed in 238 with backache and 102 without backache which were visited at Chungnam National University from March 1980 to July 1981.The measurement of lumbosacral angle was based on a method of Fergson. The results obtained were as follows; 1. The age group of 18 to 29 years was most common in backache group and the male was affected more frequently than the female with the ratio of 1.9 to 1. 2. In patients with backache, the overall mean lumbosacral angles were 44.2±2.6 degrees in male and 35.8±2.0 degrees in female. In patients without backache, in control group, the overall mean lumbosacral angles were 32.6±0.7 degrees in male and 33.4±1.4degrees in female. 3. In control group, difference of means between male and female was about 1degrees in patients with backache, the overall mean lumbosacral angles were increased about 12degrees in male and 2degrees in female than control group. In patients with and without backache, no significant difference of lumbosacral angle between the 4 age groups was present. 4. In backache group, increased lordosis was more common and increased lumbosacral angle than the decreased lordosis. 5. In backache group, lumbosacral angle of abnormal radiologic findings in lumbosacral spine was significantly increased than control group. 6. In patients with backache, radiologic findings and its lumboscral angles were alumbosacral anomaly 56 cases (23.5%): 46.9 degrees, increased lumbar lordosis 46 cases (19.2%): 48.1 degrees, osteoarthritis 44 cases(18.5%) : 40.8 degrees, decreased lumbar lordosis 30 cases (12.6%): 29.9 degrees, in order, And these radiologic findings were similar with many other authors.
