The purpose of this study was to evaluate and compare the influence of Steroid topical irrigation and implant surface on bone healing in the irradiated rabbit tibia. Implant to bone contact surface ratio and the pattern of bone healing around hydroxyapatite(HA) coated implant and pure titanium (Ti) implant which were inserted into the irradiated rabbit tibia were compared. 16 Korean house mature male rabbits were used as experimental animal. Each rabbit received 15 Gy of irradiation. 4 weeks after the irradiation, two holes were prepared in the irradiated tibia of each rabbits, where two surface type of implants were inserted :1) HA coated type and 2) pure Ti type. Right before placing implants, one group of rabbit received steroid irrigation and the other group did saline. After the irrigation, two implants of HA coated type and pure Ti type were inserted into the tibia of each rabbits. Each rabbit were sacrificed at 2nd, 4th, and 8th week after the implantation and the specimens were observed by the light microscope. The pattern of bone healing and histomorphometric analysis of the implant-bone interface were done. The results were as follows. 1. All implants inserted into the irradiated tibia of rabbit did not show any sign of clinical mobility and the bone around implants inserted into the irradiated tibia of rabbit did not show any resorption. 2. The bone to implant contact surface ratio around HA coated implants that received steroid irrigation got more bone to implant contact surface ratio than that of the saline irrigation. This result showed statistically significant(p<0.05). There was no statistically significant difference in 8th week group. 3. Though there was no statistically significant difference HA coated implants had more bone to implant contact surface ratio than pure Ti implant in 2nd and 4th groups, and there was no difference in 8th week group. 4. All implants inserted into the irradiated tibia of rabbit had exhibited successful osseointegraion.

Background: Pain due to spinal stenosis is one of the major causes of low back pain, and it sometimes does not respond to conservative treatment. We postulated that anterior epidural irrigation could be a good choice for treating lumbar spinal stenosis patients. However, the effects and theoretical basis of anterior epidural irrigation have not been investigated for spinal stenosis. So, this study was designed to identify the clinical efficacy of anterior epidural irrigation for treating lumbar spinal stenosis. Methods: 71 patients with lumbar spinal stenosis underwent anterior epidural irrigation. Anterior epidural irrigation was performed with normal saline and a mixture of local anesthetic with steroid through a catheter under fluoroscopic guidance. The findings were evaluated with using visual analogue scales for low back pain and leg symptoms. Results: Relief from low back pain and leg pain was observed for up to 12 months after anterior epidural irrigation. None of the patients showed any deterioration of their motor or sensory deficits during follow up. Conclusions: Anterior epidural irrigation is effective for the relief of back and leg pain in spinal stenosis patients.

In this study, the rate of bone formation and the pattern of bone to implant contact surface around HA coated implant and pure Ti implant inserted into the irradiated tibia of rabbit were compared. Sixteen mongrel mature male rabbits were used as experimental animal. Each rabbit received 15 Gy of irradiation. Four weeks after irradiation, two holes were prepared on the tibia of each rabbit for placement of HA coated type and pure Ti type implants. Prior to implant placement, one group received steroid irrigation and the control group was similarly irrigated with normal saline. This was immediately followed by placement of the two different types of implants. Postoperatively, tetracycline was injected intramuscularly for 3 days. For fluorescent labelling, 3 days of intramuscular alizarine red injection was given. 2 weeks before sacrifice, followed by intramuscular calcein green on the last 3 days before specimen collection. Each rabbit was sacrificed on the second, fourth, sixth and eighth week after the implantation. The specimens were observed by the light microscope and the fluorescent microscope. The results were as follows; 1. All implants inserted into the irradiated tibia of rabbit were free from clinical mobility and no signs of bony resorption were noted around the site of implant placement. 2. Under the light microscope, new bone formation proceeded faster around implants that received steroid irrigation compared to the control group irrigated with saline. Bone to implant contact surface was greater in the steroid irrigated group than the saline irrigated group. Therefore, better initial stabilization was observed in the group pretreated with steroid irrigation. 3. Under the light microscope. HA coated implants showed broader bone to implant contact surface than pure Ti implants, and HA coated implants had better bone healing pattern than pure Ti implants. 4. In the steroid pretreated group, acceleration of bone formation was demonstrated by fluorescent microscopy around the 2, 4 weeks group and the 6 weeks HA coated implant group. The difference in the rate of bone formation proved to be statistically significant(P<0.05). Faster bone formation was noted in the saline irrigated group in the 6 weeks pure Ti implants and 8 weeks group. The difference was not statistically significant(P<0.05). 5. For the rabbits that were sacrificed on the second and fourth week after the implant placements, the rates of bone formation around HA coated implants proceeded faster than those around pure Ti implants under the fluorescent microscopy. For the rabbits that were sacrificed on the sixth week after the implant placements, the rates of bone formation around pure Ti implants proceeded faster than those around HA coated implants under the fluorescent microscopy. But this result did not show statistical significance (P<0.05) For the rabbits that were sacrificed on the eighth week after the implant placements, the rates of bone formation around HA coated implants proceeded faster than those around pure Ti implants under the fluorescent microscopy. This result was statistically significant (P<0.05).

Objectives : Through the literatures on the effets of Bufonis Venenum, we are finding out the clinical possibility and revealing the more effective to intractable diseases. Methods : We investigated the literatures of Oriental Medicine and experimental reports about Bufonis Venenum. Results : 1. Bufonis Venenum is made of bufonidae bufo bufo gargarizans cantor or bufo melanostictus schneider of white serum which secreted from parotid gland or dermato gland, and it is dried for using. 2. In oriental medicine, Bufonis Venenum has been mainly used on the tumors, cacanthrax and dermatic disease, and then it has been clinically used on infantile athrepsia, tetanus, sore throat, toothache, and so on. 3. The pharmacological effects of Bufonis Venenum are cardiotonic, respiration stimulation, depressor or vasopressor, topical anesthcsia, hallucination, striped muscle stimulation, antiasthmatic, antibacterial, antiinflammatory, anticancer, diuretic, immuno effects, etc. 4. Bufonis Venenum is largely divided in ether binding steroid compound, hydroxyl steroid compound, carboxyl or aldehyde steroid compound, indole compound, and adrenaline, cholesterole, etc. 5. Symptoms of Bufonis Venenum poisoning in digestive system are vommitig, abdominal pain, diarrhea, dehydration, in circulatory system are palpitation, shock, bradycardia, in nervous system are vertigo, somnolentia, muscle-tendon reflex weakness, and critical conditions to tissue necrosis and heart attack. 6. Ways to treat Bufonis Venenum poisoning include gastric irrigation with $0.2~0.5\%$ potassium permanganate fluid and atropine $0.5{\sim}1.0mg$ subcutaneous injection. From the chinese book of Bon Cho Gang Moke(本草綱目), if white serum of Bufonis Venenum enter the eyes, it happens the edema and pain. And then washed the eyes by juice of Lithospermi Radix(紫草) that the edema is removed. Conclusions and Discussion : The results from above literary studies show that prescriptions and Aqua-acupuncture of Bufonis Venenum could be clinically used to sedative, anticonvulsant, antibacterial, antiinflammatory, anticancer and topical ataralgesia. However it is expected that pharmacological and side effects of Bufonis Venenum are further studied.

Caudal epiduroscopy has been introduced as an alternative technique for direct injection of epidural steroid and lysis of adhesion. Futher, it gives a better understanding of the role of epidural adhesion in recurrence of sciatica and low back disorder after surgery. We experienced a clinical application of flexible fiberoptic epiduroscope inserted through the sacral canal. A 37-year-old woman was suffering from right lumbar radiculopathy after an operation for a herniated disc. A series of volumetric caudal steroid injections and physical therapy had little effect on her symptoms. Patient was thought to be a good candidate for epiduroscopy. Flexible flberoptic epiduroscopy was as follows: 60 ml of normal saline irrigation and epidurogram, 40 mg of triamcinolone in 10m1 of normal saline was directed around right L5 nerve root. The following morning, patient reported reduced pain in her leg.

Cystitis and proctitis are defined as inflammation of bladder and rectum respectively. Haemorrhagic cystitis is the most severe clinical manifestation of radiation and chemical cystitis. Radiation proctitis and cystitis are major complications following radiotherapy. Prevention of radiation-induced haemorrhagic cystitis has been investigated using various oral agents with minimal benefit. Bladder irrigation remains the most frequently adopted modality followed by intra-vesical instillation of alum or formalin. In intractable cases, surgical intervention is required in the form of diversion ureterostomy or cystectomy. Proctitis is more common in even low dose ranges but is self-limiting and improves on treatment interruption. However, treatment of radiation proctitis is broadly non-invasive or invasive. Non-invasive treatment consists of non-steroid anti-inflammatory drugs (NSAIDs), anti-oxidants, sucralfate, short chain fatty acids and hyperbaric oxygen. Invasive treatment consists of ablative procedures like formalin application, endoscopic YAG laser coagulation or argon plasma coagulation and surgery as a last resort.

Pregnancy rhinitis is a relatively common condition. It is characterized by the presence of nasal symptoms, especially nasal congestion, not present prior to pregnancy, but typically present during the last 6 or more weeks of pregnancy, without other signs of respiratory tract infection or any known allergic causes, and disappearing completely within 2 weeks after delivery. Nasal saline irrigation, intranasal steroid spray, and oral antihistamines are usually recommended as the first line of treatment for rhinitis. However, most pregnant women refuse medical treatment for pregnancy rhinitis because of the fear of teratogenicity. Severe pregnancy rhinitis increases the risk of snoring, which has been suggested as having adverse effects on the fetus. In cases where the patients are unable to control their symptoms, pregnancy rhinitis can negatively affect the quality of life (QOL) as well as the pregnancy outcome. Therefore, special caution is required for determining the appropriate diagnosis and treatment modalities for pregnancy rhinitis. Here, we report for the first time, the successful treatment of pregnancy rhinitis that was unresponsive to conservative management and medical therapy by using microdebrider-assisted inferior turbinoplasty at the final stages of pregnancy, along with a review of the relevant literature.
