The authors studied the course of the infrapatellar branch of the saphenous nerve in 36 cadaver legs, with particular reference to its relationship to the sartorius muscle. In 19 (52.8%) the infrapatellar nerve passed through the sartorius, in 15 (41.7%) it passed over the sartorius before distributing to the antero-medial aspect of the knee. In two the nerve branched: in one both branches penetrated the sartorius and in the other, one branch penetrated and the other passed over the sartorius. The authors could not find any case in which the nerve passed through the tendon of the sartorius or passed under the sartorius. These findings explain why few cases of entrapment neuropathy of the infrapatellar branch clinically need surgical treatment.

16 cases of entrapment neuropathy of the axillary nerve in the quadrilateral space were reported. Etiology, symptomatology, differential diagnosis and therapy of this disorder were discussed. The complaints of the patients were pain on the dorsal and lateral aspect of the shoulder, especially in abduction, external rotation and horizontal abduction of the shoulder.Objective findings were sensory disturbance in the autonomo u s zone of the axillary nerve, muscle atrophy of the deltoid and the terses minor muscle and tenderness on the quadrilateral space. But in mild cases muscle atrophy was not observed. In two cases partial muscle spasmus of the deltoid and the teres minor muscle and tenderness on them were observed. In one case with muscle atrophy the electromyographic investigation showed neurogenic changes of the deltoid and the teres minor muscle: motor unit action potential were long in duration, high in amplitude and polyphasic. This case was operated on and satisfactory result followed neurolysis. In other cases there was a good response to local infiltration of steroid and procaine hydrochloride. Our cases suggest that this neuropathy might also be considered in the differential diagnosis of a patient presenting with shoulder pain. Useless diagnostic procedures and treatment can be avoided if the physician is aware of this condition.

We report three cases of femoral nerve paresis. Case 1 was a 25-year-old male, who was admitted to hospital complainning of left thigh pain. On examination he had tenderness in his left inguinal area. Neurological examination revealed a weakess of the quadriceps on the left, and diminished sensation on the anteromedial aspect of his left lower extremity. The mechanism of injury was not clear in this case. Case 2, a 56-year-old male had progressive muscle weakness and numbness in the right lower extremity. He had received cobalt radiation therapy 16 years previously. Clinical examination revealed a firm hypertrophic scar with tenderness in the right inguinal area, and neurological examination showed quadriceps weakness and sensory disturbance of the anteromedial surface of the right thigh nd leg. Case 3, an 18-year-old male complained of gait disturbance and sever pain around theleft inguinal area and numbness over the left thigh. “The patient was a hemophiliac who had been unde the care of a pediatrician”.Neurolysis was performed in two cases, and the other patient was treated with bed rest and replacement therapy. In all cases, symptoms improved after treatment.

We reviewed twenty-three cases of carpal navicular fracture visited our clinic in the past ten years. The length of follow up were one to seven years, with an average of fourty-five months. Prognosis of proximal part fractures were the worst (one fair and one poor) in comparison to that of middle and distal part. Eight cases, all of which were the symptomatic delayed union or non-union, were operated by the bone graft with or without the styloidectomy. The results of operated cases were four good, three fair and one poor. On the other hand, nontreated cases were all evaluated as good and excellent, but most of them had little symptoms when they visited our clinic. The characteristics of their roentogenograms were the absence of bone absorption at the fracture site and the stability in stress roentogenograms. Although many authors refered the carpal osteoarthritis following unstable non-union of the navicula, the result in this series may suggest that surgeons must be prudent in treatment of asymptomatic and stable non-union.

The authors dissected 72 paired arm to study the anatomy of Gantzer's muscle. The dissection explored course of the median nerve from the elbow to the distal end of the forearm. The following anatomical structures and variations were noted;(1) The presence of a Gantzer's muscle, as well as its relationship to the median and anteriorinterosseous nerves.(2) The origin and insertion of Gantzer's muscle.Results: Gantzer's muscle arose from the medial epicondyle of the humerus in 45 arms (90%), from the coronoid process of the ulna in 3 arms (6%), from the intermuscular fascia in 1 arm (2%), and from a double origin- the medial epicondyle and the coronoid presess-in 1 arm (2%). Insertion was to the proximal part of the tendon of the flexor pollicis longus muscle in all arms.Gantzer's muscle always lies posterior to the median nerve. In 12 out of 50 arms, the muscle passed posterior to the anterior interosseous nerve, and in the remaining 38 arms, the anterior interosseous nerve ran proximal to the muscle along its proximal border and never cross Gantzer's muscle and its tendon.Based on these findings, the authors concluded that Gentzer's muscle rarely contributes to anterior interosseous nerve compression in the proximal forearm.

Two patients with compression neuropathy of the superficial radial nerve are presented.Case 1: A 71 year-old female visited our clinic in November, 1995 with a one month history of pain in the dorsum of both hands.Clinical examination revealed paresthsia on the radial half of the dorsum of her hand and tenderness on dorsal area of the distal forearm, where the superficial radial nerve pierced the deep fascia of the forearm. The patient was operated on after failure of conservative treatment for Cheiralgia Paresthetica.At exploration a membranous tissue traversing over the nerve was seen and incised, and a shallow indentation was seen on the nerve under the membrane.After the operation her pain disappeared and has not recurred.Case 2: A 38 year-old male presented in 1991 with dysesthesia on the dorsum of his right hand and a tumor on the dorsum of his right forearm.He also reported pain on the dorsal side of his right hand. Three years later he recognized a small tumor on the dorsal side of his right distal forearm and dysesthesia on the dorsum of his right hand. Examination revealed sensory loss limited to the area supplied by the superficial radial radial nerve and a tumor on the dorsal side of his right forearm.Partial resection of the tumor and neurolysis was carried out, under the diagnosis of a compression neuropathy of the superficial radial nerve due to a forearm tumor.The pathological diagnosis was a nalignant fibrous histiocytoma.The patient's pain disappeared after the operation but recurred one month later. The patient died four months later due to lung metastasis.

In the previous paper, it was found that top dressing with nitrogenous fertilizer at full heading stage increases their percentage of ripened grains and results in an increase in yield. On the other hand, it is known that the protein content of rice is increased by the application of nitrogenous fertilizer after heading stage. Based on those results, the present experiments were carried out to prove the possibility of increasing the protein yield and the nutritional value of rice by nitrogen dressing. Basal dressing and top dressing at panicle formation stage did not always affect the total nitrogen content ( : protein content) but top dressing at full heading stage increased the total nitrogen content by 15∼30 per cent. In the case of increasing not only the total nitrogen but the grain yield by top dressing at full heading stage, the total nitrogen yield was greatly increased by the interaction. With respect to a given quantity of top dressing after full heading stage (2∼8 Ng/m2), it was shown that the more the fertilizer applied, the more the total nitrogen content was increased. When an identical amount of the dressing was applied in the period from full heading stage to 30 days after it, it was the more effective at the nearer stage to full heading. The total nitrogen was less in milled rice than in brown rice and the decreasing rate of total nitrogen by milling was lower in the brown rice of high total nitrogen content increased by top dressing at full heading stage. This finding indicates that the increased protein is stored in the endosperm. The total nitrogen content in both the brown and the milled rices showed negative correlations with lysine and methionine contents to 16g total nitrogen but positive correlations with lysine, threonine and methionine contents on dry matter. As the results, it is presumed that top dressing at full heading stage serves to increase the protein content and the nutritional value of rice, and also the protein yield in case of the percentage of ripened grains being increased.
