In the microsurgical dissection of the lateral wall of the cavernous sinus, interrelationships of its nerves have been studied in 100 Korean adult half heads. And in the serial coronal section of the cavernous sinus in 10 half heads, the structures of the lateral wall have been studied. The relationships of the nerves of the lateral wall were classified to five types according to the course of the trochlear nerve. Each length of the Parkinson's triangle and the angle between trochlear and ophthalmic nerves were measured. There data were compared with those of the other races. The lateral wall of the sinus was composed of two layers. The orientation of the fibers of the deep layer was variable in regions. The oculomotor nerve was enveloped with sheath extended from dura mater and it was connected with deep layer of the lateral wall. The trochlear nerve was enveloped with sheath formed y division of innermost part of the deep layer. The venous sinus was found between the two layers of the lateral wall. The neurosurgical significance of the lateral wall of the sinus was discussed.

The authors analized the 98 cases of cervical spine injuries without fracture or dislocation by hyperflexion/hyperextension of the neck. The peak incidence of the age was in the second to fourth decades(69.4%). There was a male preponderance with a sex ratio of. 1.8 : 1. Sources of trauma were motor vehicle accident, object falling on and motorcycle accident in the order of frequency. The common mechanisms of injury were flexion-extension, extension and flexion injury in the order of frequency. There were 10 cases of cervical cord injury without fracture or dislocation and operative management was given in 6 cases of them. The most common preexisting disease was congenital cervical stenosis. Surgical modality such as laminectomy, laminoplasty and anterior decompressive procedure made them improved. The authors discuss the mechanism of injury and surgical management of the patients with cervical cord injury in the absence of concomittent fracture or dislocation.

PURPOSE: To recanalize the occlusive lesion of superficial femoral artery at origin site by retrograde approach via popliteal artery. MATERIALS AND METHODS: 15 patients, who were poor surgical candidates due to coronary artery disease and who had severe occlusive lesion of superficial femoral artery close to its origin with good distal runoffs to popliteal artery, were selected. Patients were all~men and range of age were from 53 years to 66 years (mean age:63 years). Range of lesion length were from 15cm to 30cm (mean length:22.4cm). Localization of popliteal artery was done with Doppler stethoscope or "road-map" DSA. The method of recanalization were transluminal endarterectomy catheter (TEC), TEC and angioplasty, thrombolysoangioplasty (TLA). RESULT: Retrograde puncture of popliteal artery were done in 15 patients successfully. TEC & PTA was performed in 9 patients, TEC only in 2 patients, and TLA & PTA in 2 patients. During the follow-up period of 5 months to 2 years reocclusion did not occurr in 10 patients except for 1 patient with poor cardiac output in whom it occured 1 day later. Remained 4 patients were lost in follow up. Any neurologic or vascular complication did not occur. CONCLUSION: Retrograde approach of superficial fernoral artery via popliteal artery in patients with difficult vascular intervention by common method provides a useful, alternative recanalization method.

The development of the cardiac ganglion was studied by electron microscopy in human fetuses ranging from 30mm to 270mm crown rump length. At 40mm fetus, the cardiac ganglia were observed in the adventitia of both the aorta and pulmonary artery, superior aspect of the left and right atrium, and interatrial septum. The cardiac ganglia were comprised of clusters of undifferentiated cells, neuroblasts, and unmyelinated nerve fibers. The ganglia were small and uncapsulated until 70mm fetus. At 70mm fetus, the cardic ganglia consisted of neuroblasts, satellite cells, and unmyelinated nerve fibers. Each ganglion was ensheathed in a connective tissue capsule. The cytoplasm of neuroblast contained Nissl bodies, mitochondria, coated vesicles, extensive Golgicomplex, and rough endoplasmic reticulum. Synaptic contacts between the cholinergic preganglionic axon and dendrites of postganglionic neuron were first observed. At 100mm fetus, the cardiac ganglia consisted of small clusters of ganglion cells and dendrites, together with supporting elements and blood vessels. During next prenatal stage from 170mm fetus, the ganglion cells were large and each contained a large nucleus with one or more nucleoli. The cytoplasm of ganglion cells contained much rough endoplasmic reticulum and extensive Golgi complex. Cholinergic preganglionic axons were numerous and interposed between the satellite cells. Adrenergic axons were rarely observed. A great number of synaptic junctions between the cholinergic preganglionic axon terminals and the dendrites of postganglinic neuron were found, and a few axosomatic synapses were also observed. Adrenergic nerve terminals did not seem to be involved in the synaptic transmission. The cardiac ganglion cells of the human fetal heart were innervated only by cholinergic nerve.

Human papillomavirus (HPV) 16/18 is a causative agent of uterine cervical carcinoma. HPV 16/18 can alter cell cycle regulation through apoptosis. Bcl-2 is an important regulatory gene of apoptosis. A study was done to evaluate the relation between HPV 16/18 and bcl-2 and apoptosis in 21 cases of carcinoma in-situ (CIS), 5 cases of microinvasive carcinoma and 23 cases of invasive squamous cell carcinoma. HPV 16/18 was detected by hybrid capture system (HCS), bcl-2 protein by immunohistochemical method and apoptosis by using the hematoxylin-eosin stained slide. The results were as follows: Expression of the bcl-2 protein was 43% (9/21) in CIS and 26% (6/23) in invasive carcinoma. Expression of the bcl-2 protein was 42% (5/12) in CIS with HPV 16/18 infection, 44% in CIS without HPV 16/18 infection, 20% (2/10) in invasive carcinoma with HPV 16/18 infection and 31% (4/13) in invasive carcinoma without HPV 16/18 infection. Mean apoptotic index (mAI) was 3.36 in CIS, 5.23 in microinvasive and 6.25 in invasive carcinoma. mAI was 3.66 in CIS with HPV 16/18 infection, 2.86 in CIS without HPV 16/18 infection, 6.18 in invasive carcinoma with HPV 16/18 infection and 6.30 in invasive carcinoma without HPV 16/18 infection. Based on these results, we conclude that there are no correlation between HPV infection and bcl-2, and between HPV infection and apoptosis in invasive and in situ carcinoma of the uterine cervix, and apoptosis is increased according to tumor progression.
