Study of the healing process after transplantation of pasteurized bone grafts in rabbits.

Different bone allografts (pasteurized, autoclaved, and frozen) were compared based on their osteoinductive properties. Our primary purpose was to examine the biologic qualities of pasteurized allografts, as pasteurization inactivates most viruses transmitted by transplantation. Frozen, pasteurized, and autoclaved allografts were packed into a standard defect of rabbit ulna. The animals were sacrificed at 2 and 4 weeks after surgery. The parts of bones with experimental defects were explored en bloc, and a roentgenogram was carried out. Ulna bone samples were then embedded in methyl-methacrylate. Roentgenograms showed that after 2 weeks, calluses were well-formed, but irregular in shape in all 3 types of allografts. After 4 weeks, the calluses were regular in shape in all but the autoclaved grafts. After 2 weeks, the healing processes had begun in the frozen and pasteurized grafts, with the reaching approximately the same stage, while in the autoclaved grafts these processes were not seen and the bone particles were surrounded by connective tissue without any changes. After 4 weeks, osteoinductive processes were very strong, with the first signs of complete bone remodeling at the bone edges of the defect in pasteurized and frozen allografts. The osteoinductive values of these 2 types were very high and similar. Autoclaved allografts, on the other hand, had very low osteoinductive values, as they were still at the very beginning of the healing process. Histomorphometric analysis revealed a significant difference in both newly formed osteoid thickness and osteoblast number per microm of bone surface in all experimental groups (P &#60; 0.005). Values of osteoid thickness and osteoblast number were significantly higher in both frozen and pasteurized grafts when compared with the autoclaved ones (P &#60; 0.005). Osteogenic properties of pasteurized bone allografts were preserved, and the allografts have been gradually replaced with newly formed bone. As such, pasteurized bone grafts from a bone bank have approximately the same biologic validity as frozen grafts, while autoclaved grafts impair bone healing.</p

Two Different Manifestations of Locked-InSyndrome

Locked-in syndrome (LIS) is an entity that usually occur a consequence of the lesion of ventral part of pons. Etiology of locked-in syndrome can be vascular and nonvascular origin. Locked-in syndrome usually occurs as a consequence of thrombosis of intermedial segment of basilar artery that induces bilateral infaction of the ventrobasal part of the pons. Additionally, LIS can be caused by trauma which often leads to posttraumatic thrombosis of basilar artery. The incidence of locked-in syndrome is still unknown. The basic clinical features of locked-in syndrome are: quadriplegia (a consequence of disruption of corticospinal pathways located in ventral part of pons), different stages of paralysis of mimic musculature, paralysis of pharynx, tongue and palate with mutism and anarthria. The patient can not move, but is conscious and can communicate only by eye movements. Two patients with locked-in syndrome were present in this article. In the first case, the patient had classic locked-in syndrome that was first described by Plum and Posner1. Other patient had incomplete form of locket-in syndrome which was first described by Bauer2. In these two patients locked-in syndrome occurred as a consequence of trauma. In the first patient locked-in syndrome was caused by direct contusion of ventral part of pons while in other patient locked-in syndrome was a consequence of posttraumatic thrombosis of vertebrobasilar artery. The introduction of anticoagulant therapy, besides the other measures of intensive therapy, has shown complete justification in the second patient. The gradual partial recovery of neurologic deficit has developed in the second patient without any additional complications

NEW CONCEPT OF MARKETING IN THE AGRO-BUSINESS

Based on new social approach to marketing between Green and Philanthropic marketing, a new concept of marketing in Agro-Business is developing. Its development is influenced by difficulty to find new sources of competent advantages of the companies as well as the requests derived from the society for protection and better care of the consumer since the rate of his mortality has rised due to bad food and fatiness. Supporters of this concept create and try to satisfy all the necesities of health consumer by offering a health and safe products and good service. Therefore they take into consideration the quality of living conditions within social community, protecting natural envirenments at the same time. New concept of marketing in agro-business is the marketing of safe and health food which will intesify the involvement of SCG companies into integrating processes

The plane-to-cellular-to-dendrite transition of the shape of the crystallization front during the crystallization of Al–Cu alloys

The evolution of the crystallization front from a planar to a dendritic one as a function of the GL/(Rc0) parameter was investigated during the crystallization of Al–Cu alloys by the vertical Bridgman method. Six series of alloyswith different initial compositions of Cu were solidified at different growth rates. A mathematical model for the heat transfer during vertical Bridgmen crystal growth was developed. The model was solved using the finite element method. The temperature gradient in the melt at the beginning of crystal growth was calculated using the obtainedmodel. Discrete stages of the crystallization front were identified in the experiments, as the ratio GL/(Rc0) decreased

ULTRASOUND-EXPLORED ANATOMIC CHARACTERISTICS OF THE RENAL SINUS IN HEALTHY CHILDREN

In 195 with no manifest urinary tract disease, of the one to seven years of age,the ultrasound was used to determine the renal sinus dimensions (length and width),Their correlation with age and the kidnev dimensions was examined. The real-timemechanical sector scanner (ALOKA SSD 500) was used with convex probes of 3,5and 5 MHz in the supine position and in the counter-lateral body decubitus. The sinus dimensions kept on increasing continuously during the analysis period, mostintensely during the fifth year of age. The sinus enlargement was in a bettercorrelation with the kidney growth than with the childrens age. Still, there is anevident slight lagging behind in the sinus dimension growth comparing to the kidneydimension growth

Foveal Avascular Zone in Normal Tension Glaucoma Measured by Optical Coherence Tomography Angiography

Aim. To measure diameter of foveal avascular zone (FAZ), FAZ area, and vessel density using Optical Coherence Tomography Angiography (OCT-A) in patients with normal tension glaucoma (NTG) and to establish the possible role of OCT-A in diagnosis and follow-up of patients with NTG. Methods. Twenty-one eyes of 21 patients with NTG and 30 eyes of 30 healthy subjects underwent complete ophthalmic examination as well as OCT-A on ZEISS AngioPlex. 3×3 macula scans were used to measure vertical, horizontal, and maximum diameter of FAZ by two graders. Mean values and interobserver variability were analyzed. Image J was used for analysis of FAZ area and vessel density. Results. Mean vertical diameter (t=5.58, p<0.001), horizontal diameter (t=3.59, p<0.001), maximum diameter (t=5.94, p<0.001), and FAZ area (t=5.76, p<0.001) were statistically significantly enlarged in the NTG group compared to those in the control group. Vessel density (t=-5.80, p<0.001) was statistically significantly decreased in the NTG group compared to that in the control group. Conclusion. OCT-A could have an important role in the future in diagnosis of patients with NTG. In patients with NTG, there is larger FAZ area, while the vessel density is reduced in comparison to the control group

Isolated Spleen Metastases of Endometrial Cancer: A Case Report

Background: Isolated splenic metastases from endometrial cancer, which is a relatively common malignancy, are extremely rare findings; to date, only 14 cases have been reported in the literature. Case Summary: We report a patient with isolated splenic metastases of endometrial cancer 3 years after radical surgery of the primary tumor. The patient was successfully treated by splenectomy and six cycles of paclitaxel. Fifty months after splenectomy, she was alive and well, and with no evidence of disease. Conclusion: Isolated spleen metastasis of endometrial cancer is very rare. Radical surgery and adjuvant therapy may offer excellent long-term survival
