With the progress of farming and foresting, the demand of agricultural pesticide has been remarkably increased and accordingly, its intoxication has been widely publicized. Among the pesticides, organophosphorus chemicals has been believed to be almost nontoxic because they are not accumulative in the tissue. This study is attempted to examine the effects of DDVP which has been used most frequently on the kidney. And they were divided into normal and experimental groups. The results obtained from this experiment are as follows. 1) BUN, serum creatinine are increased in the group of DDVP administered while serum cholinesterase is suppresed significantly. 2) Microscopically, swelling and degeneration of tubular cells and hyaline casts in tubules. Ultrastructually swelling of mitochondria, partial fragmentation of cristae and electron dense bodies in the kidney are observed in the group of DDVP administered.

This presentation is a case of osteomalacia, the cause of which was a nutritional deficiency. The patient was a 42-year-old female who had pseudofractures of ribs, ulnae, pelvic raml, the right second metacarpai bone and both femoral necks. Following treatment by medication combined with internal fixation of the femoral necks, the result was good.

The extraction rates of biogenic amines such as 5-hydroxytryptamine(5-HT) and norepinephrine(NE) in pulmonary endothelium, and the permeability of human serum albumin(HSA) to pulmonary epithelium were measured in experimental adult respiratory distress syndrome(ARDS), in order to evaluate their usefulness for the early recognition of ARDS. Sixteen mongrel dogs(body weight, 13+/-0.9 kg) were divided into 3 groups; Oleic acid 0.06 ml/kg was injected to 6 dogs(M group) and oleic acid 0.12 ml/kg to 6 dogs(S group). Four dogs were used as a control group. The extraction rates(%) of 14C-5-HT and 3H-NE, the blood concentration of (99m)Tc-HSA, hemodynamic changes and changes of arterial gas profile were measured and compared among three groups. In control group with 100% oxygen ventilation, the extraction rates of 14C-5-HT, 3H-NE and the blood concentration of 99mTc-HSA were not changed. In M group, the extraction rate(%) of 14C-5-HT was decreased from 61.5+/-3.1 to 43.8+/-5.2 in 10 minutes, and such decreased extraction rate(%) was maintained for 2 hours. The extraction rate(%) of (3)H-NE was decreased from 32.3+/-3.6 to 19.5+/-2.5 in 10 minutes. In S group, the extraction rate(%) of 14C-5-HT was decreased from 60.9+/-5.1 to 23.2+/-5.7 in the first 10 minutes, and the extraction rate(%) of H-NE was decreased from 30.1+/-4.3 to l3.1+/-1.9 in 10 min, and decreased slowly thereafter. The blood concentration of 99mTc-HSA was decreased significantly in M group and more in S group compared with control group during two-hour observation. These results suggest that measuring extraction rates of biogenic amines couid be applied for early recognition of ARDS, however, the change of blood 99mTc-HSA concentration could not be applied for early recognition of ARDS, because it has poor correlation to the progression of respiratory failure.

PURPOSE: To identify the changes of bony landmarks with rotation and to compare the reliability and accuracy of Perdriolle's method before and after training on the exact bony landmarks. MATERIALS AND METHODS: Simple A-P radiographs were taken with rotation from 5 degree to 50 degree at 5 degree interval using 10 dry human vertebrae (2 sets of T3, T6, T9 8 L3) with no bony abnormality. Axial rotation was measured before and after training on the exact bony landmarks by three observers, twice for each radiographs. Repeated measures of ANOVA were used for inter- < intraobserver variance and regression analysis for root mean square error and deviation of differences. RESULTS: Mamillary process, inner margin of lamina, proximal and distal costovertebral joints, upper margin of concave pedicle and tip of the transverse process on the convex side confused the exact outline of the pedicle, while neural foraminal margin was helpful in identifying the location of the indistinct convex pedicle and concave vertebral border. Of the 660 measurements before and after training 372 and 397 errors were made, respectively, of which 88.9% and 88.5% were within +/-5 degree(P > 0.05). Incidence of error greater than 5 degree was high at upper thoracic vertebra and 20 degree-40 degree of rotation regardless of training. The effects of training, however, was greatest at T3 and 20 degree-40 degree of rotation. Inter- < intraobserver variance was diminished at T3 and at the rotation between 20 degree-40 degree after training. CONCLUSIONS: We could conclude that training on the exact bony landmarks did not reduce the overall error incidence. Accuracy and reliability, however, was increased at T3 after training and the efficacy of training was more evident in moderate vertebral rotation than in small or large vertebral rotation.

Any foreign body in the esohagus means an acute danger because of the impending perforation followed by mediastinitis, the impending erosion of bigarteries, and impending aspiration in the care of esorhageal occlusion. Nowadays, foreign body can reliably be removed hy endoscopy, and do not perforate the wall, not changed their form. Complication at the endoscopic extraction of foreign body, that requre surgical intervention are very rare. We presented a case of esophageal foreign body complicated with esophageal ulcer in a 83 years old male.

PURPOSE: The purpose of this article is to study whether the Doppler ultrasound differentiate obstructive hydronephrosis from nonobstructive hydronephrosis in sonographically diagnosed hydronephrosis. MATERIALS AND METHODS: We studied 35 kidneys of 27 patients with hydronephrosis which were diagnosed with sonography. Resistive indices were calculated from Doppler waveforms at the level of interlobar or arcuate arteries. We divided the materials into two groups with obstructive and nonobstructive hydronephrosis according to the findings of intravenous pyelography, retrograde pyelography, and anterograde pyelography. These were compared with normal control group(20 kidneys in 10 persons). We also grouped patients regarding to the duration after onset of clinical symptom, and graded the hydronephrosis into three group according to sonographic findings. We analyzed the correlations of the above sonography and clinical findings with resistive index. Hydronephrosis was obstructive in 20 kidneys(in 17 patients) and nonobstructive in 15 kidneys(in 10 patients). RESULTS: There was statistically significant difference between the mean resistive indices in obstructive hydronephrosis(0.74 +/- 0.02) and that in nonobstructive hydronephrosis (0.60 +/- 0.02)(p<0.05). Also there was no difference between the mean resistive indeces in nonobstructive hydronephrosis and that in normal control group(0.59 +/- 0.07)(P > or = 0.05). CONCLUSION: The use of Doppler sonography can be helpful in detecting the presence or absence of true obstruction in patients with hydronephrosis.
