Familial adenomatous polyposis(FAP) is an inherited autosomal dominant disorder characterized by the appearance in early life of numerous adenomas of colon and rectum. According to the recent studies, familial polypolis is a disease which produces polypoid lesions not only in the large intestine but also in the stomach duodenum, ileum and jejunum. The natural course of extracolonic lesions is variable, but the colonic polyps are associated with high incidence of cancer. The risk of malignant change is virtually 100% if untreated. The authors report a case of FAP in a 36-year-old-female who presented colorectal polyposis with multiple adenomas of the gallbladder. A review of literature with emphasis on the association of adenoma of the gallbladder was made.

Solar urticaria is a fairly uncommon but Well recognized clinical entity characterized by erythema and wheal with itching immediately following exposure to sunlight or artifical radiation. A 33-year-old female had a six-year duration of urticaria, tightness of chest and dizziness that appeared within 15 minutes of exposure to sunlight. The action spectrum of this patient was between 320 and 400nm and the passive and reverse passive transfer test were negative. Solar urticaria of our patient appeared to belong to type g in the classification of Harber et al(1963). The patient was treated with antihistamines and repeated exposure to sunlight for inducing tolerance. After 3 months of the treatment, the symptoms did not appear even after 3 hours of exposure to sunlight.

Inflammatory polyposis of the colon is rare portion of the colon polyp entity. We experienced three patieats who suffered from colitis of unknown'etiology and discovered membranous retkular with/ without filiform polyp in the distal sigmoid colon of the them. Case 1, 56-year-old female, combined with basaloid cercinoma of the rectal canal that confirmed by pathology after abdominoperineal resection. So we obtained specimen of inflammtory polyp end tried to evaluate the mechanism of it. We found healed ulcer under the mucosal bridge. Case 2. 55-year-old male, had been suffered from irritable bowel syndrome. Prior to visit outpatient clinic, he complained tenesmus with diarrhea for a week. Inflammatory polyp was discovered by colonoacopy but his symptoms relieved by tranqulizers only. Case 3. 57-year-old male, has been a good health. He undertook colonoscopy for routine check thst revealed membranous reticular with filiform inflammatory polyp from distal sigmoid colon to hepatic flexure. Such shape of inflammatory polyp was not documented in Korea, so we reported three cases of it with review of the literature.

The complicate neurvascular contents and anatomic location on the cavernous sinus(CS) have long been considered a true "no man's land" for direct surgical approaches. But recent work focusing on the microsurgical anatomy of the CS and its adjacent structures has made a critical contribution to our understanding and capabilities in dealing with neoplasms involving the CS, and direct surgery within the CS I s gaining wider acceptance. Fourteen patients with neoplasms arising in or involving the CS had operations between June 1989 and May 1995 in our institution. The follow-up period ranged from 2 months to 51 months. The patients age range was 28 to 61 years, with an average age of 45 years. Although many approaches to the CS have been described, we prefered the pterional approach with or without zygomatic osteotomy. Usually, we also performed orbital roof and optic canal unroofing anterior clinoid process removal, and superior orbital fissure opening. Surgical treatment consisted of total removal in two patients subtotal removal in eight, partial in three, and biopsy in one. The histologies of these patients showed eight meningiomas two neurinomas, one invasive pituitary adenoma, one chondroid chorodma, one chondrosarcoma, and one fibrosing inflammatory pseudotumor. Postoperative morbility included cerebral infarction in one patient, cerebral ischemia with inflammatory pseudotumor. Postoperative morbidity included cerebral infarction in one patient, cerebral ischemia with transient hemiparesis in three, brain swelling in two, intracerebral hemorrhage in two, and transient diabetes insipidus in one. When we compared cranial nerve function between preoperative and postoperative period, we found that most of the patients tended to remain the same with respect to their preoperative function, although some notable improvements and deteriorations occurred. No cases of CSF leakage, meninigitis and postoperative death were encountered in our series. Although the number of cases and the follow-up.

PURPOSE: The present study was performed to determine the optimum conditions(RPM, load, sharpness of drill) for drilling human cortical bone with standard drill, and to evaluate the histological changes occuring in bone after drilling. MATERIALS AND METHODS: in experiment I, we measured temperature elevations and the durations of temperature elevation in cadaveric femoral cortices at specific distances from the drill hole wall while drilling. The effects of drilling force, speed and new versus worn drill on the termperature were determined. In experiment II, we also measured temperature elevations in the same manner in porcine femoral cortices and evaluated the histological changes occuring in bone after drilling. RESULTS: In experiment I, the most significant temperature elevation(68.4degrees C ) was found when worn drill was used. The lower drilling force and faster speed resulted in 55.1degrees C and 45.8degrees C temperature elevation, respectively. However, drill diameter was not a significant factor for temperature elevation. In experiment II, greater heat production was measured with worn drill, at lower drilling forces, at faster drill speed. The acute histologic reactions in bone were hyperemia, degeneration of osteocytes, change in bone stainability, tears, and fragmentation of the bone edges around the drill holes. The observed histological changes were proportional to the amount of trauma produced, that is, the greater the degree of thermal irritation, the greater the degree of histologic activity. CONCLUSION: In cortical drilling, greater heat production was measured with worn drill, at lower drilling forces, at faster drill speed and the greater the degree of thermal irritation, the greater the degree of histologic activity. A further study of the reaction of bone to drilling at longer intervals of time at different conditions may possibly show whether aseptic thermal necrosis could be prevented.

There exists a need to develop strategies that promote neovascularization in virtually all tissue engineering and regenerative medicine efforts. While research typically focuses on understanding and exploiting the role of angiogenic factors and vascular cells on new blood vessel formation, the activity of the immune system is being recognized to impact vascular formation and adaptation. This review will provide both an overview of the relationship of angiogenesis and the immune system, and how biomaterials may be designed to promote favorable angiogenesis by interaction between these 2 systems to promote effective vascularization.

The effects of topical Betoptic(R) 0.5% and Mikelan(R) 2% on the ophthalmic artery blood pressure and perfusion pressure were investigated in 30 healthy subjects using ophthalmodynamometer and Goldmann applanation tonometer. The subjects were divided into two groups and each has 15 healthy subjects. In a randomized, double-blind study, one eye of each subject received one drop of Betoptic(R) 0.5% or Mikelan(R) 2%, and fellow eye was received a drop of placebo. Diastolic ophthalmic artery blood pressure (OABPd), systolic artery blood pressure (OPBPs), and intraocular pressure (lOP) were measured just before and 2 hours after the instillation of the drugs. Mean ophthalmic arery blood pressure (OABPm) was calculated as OABPm = OABPd + 1/3 (OABPs - OABPd) and the perfusion pressure (PP) was calculated as PP = OABPm - lOP. The perfusion pressure (pp) was Betoptic(R)-treated group was increased by 9%, and that of Mikelan(R)-treated group was increased by 13%, these increasement were statistically significant (Both group P<0.01).

With the emergence of microbiome as a major player in many human diseases, bacteria as therapeutics are gaining significant interest. Whole bacteria or cytotoxic or immunogenic peptides carried by them exert potent anti-tumor effects in the experimental models of cancer. The use of attenuated microorganism (s) e.g., BCG to treat human urinary bladder cancer was found to be superior compared to standard chemotherapy. While bacteria alone may not offer full therapeutic benefits, modifying them with anti-tumor agents, anti-oncogenes or immunogenic antigens, either alone or in combination, will prove to be beneficial. Vectors for delivering shRNAs that target oncogenic products, express tumor suppressor genes and immunogenic proteins have been developed. These approaches have showed promising anti-tumor activity in mouse models against various tumors. These can be potential therapeutics for humans in the future and such therapeutics may become a future alternative or adjunct regimen along with conventional chemotherapy and radiotherapy. In this review, some conceptual and practical issues on how to improve these agents for human applications are discussed.
