Capsaicin, the pungent principle of hot peppers, is a neurotoxin that depletes unmyelinated primary sensory neurons (polymodal nociceptors) of neuropeptides like tachykinins. However, the role of capsaicin-sensitive sensory nerve in the production of cytokines, penicillin V (PEV)-induced active fatal anaphylaxis and other immune responses is not yet fully established. Neonatal mice were pretreated s.c. with a single injection of 10 ug of capsaicin per mouse in volume of 20 ul within 5 days of age. Using 5-8 week old mice pretreated as neonates with capsaicin, the capsaicin- pretreated and vehicle-treated control mice were examined for various parameters of immune responses described above. For the induction of active fatal anaphylaxis with PEV, 8 week old mice pretreated as neonates and age-matched capsaicin- untreated control mice were sensitized i.p. with 500 ug of PEV-ovalbumin conjugate plus 2*10(9) B. pertussis and 1.0 mg alum and challenged i.v. with PEV-bovine serum albumin conjugate 14 days later. It was found that neonatal capsaicin-pretreatment significantly enhanced contact hypersensitivity to TNCB and hemagglutination response to SRBC, but significantly inhibited the proliferation response of rnurine splenocyte to Con A and LPS. Interestingly, neonatal capsaicin pretreatment significantly inhibited the intensity of PEV-induced active fatal anaphylaxis and decreased the mortality due to anaphylactic shock. It also significantly inhibited LPS- induced production of cytokines such as TNF-a, IL-1B, IL-6, IL-10, and IL-12. The capsaicin-pretreatment also resulted in an inhibition of the activation of NF-kB. Taken together, these data showed for the first time that neonatal capsaicin-pretreatment significantly inhibited an antibiotic (PEV)-induced anaphylaxis and production of various cytokines, and suggest that capsaicin-sensitive primary sensory nerve may play an important regulatory role in active fatal anaphylaxis and cytokine production, thus potentially presenting tools for immune intervention. In particular, the data presented also indicated the possibility to selectively down-modulate cytokine production and NF-kB activation may offer a broad application for therapeutic intervention in neuroimmunological diseases and other pathological situations.

Benign solitary osteochondroma are the most common benign bone tumor, and often arise in the long bone of the extremities about 80% of lesions, particulary about the knee and the upper extremity. In rare cases, the spine is involved. We describe a case in which a solitary sacral osteochondroma compressed the lumbosacral plexus, producing sensory disturbance. The tumor was removed through the anterior midline approach. The excised mass was round, lobulated, measuring 7. 5cm×6cm, pedunculated type and the cartilage cap is complete and is 4mm in thickness.

In order to evaluate the efficacy of adenosine triphosphate (ATP) in the reduction of left ventricular afterload, we studied the hemodynamic and intrapulmonary shunt effects of intravenous ATP during ethrane-N2O anesthesia. Hemodynamic measurements and arterial and mixed venous blood gas analyses were made in ten patients before (baseline) and 10 min after. ATP infusion at 80,60,120 and 250 mcg/kg/min, respective. The results were as follows: 1) ATP produced a rapid and stable reduction in mean arterial pressure resulting from a marked decrease in systemic vascular resistance. 2) Cardiac index increased significantly by 14, 47 and 72% from baseline value after intravenous infusion of ATP at rates of 60, 120 and 250 mcg/kg/min, respectively. 3) Stroke volume index, heart rate, mean pulmonary arterial pressure, pulmonary capillary wedge pressure and central venous pressure increased significantly, whereas systemic vasular resistance and pulmonary vascular resistance decreased significantly in a dose related fashion during ATP infusion. 4) Intrapulmonary ehunt fraction increased from 5.67% to 6.73, 8.28, 9.85 and 13.38% after intra- venous infusion of ATP at rates of 30, 60, 120 and 250 mcg/kg/min, respectively. 5) Arterial oxygen tension decreased significantly after ATP infusion. These results suggest that ATP might be of value in augmentation of cardiac performance in patients with low cardiac output with high peripheral vascular resistance.

The purpose of this study was to observe the additive effect of halothane anesthesia and propranolol, and also the effect of atropine and isoproterenol on the heart rate and the blood pressure after propranolol during halothane anesthesia in human-volunteers. The results were as follows: 1) In conscious patients, 10 minutes after intravenous administration of 1.0mg propranolol the heart rate was slower but there was no significant change in the blood pressure. 2) Twenty-thirty minutes after halothane anesthesia, the heart rate was slower by 6 to 8 beats per minute: systolic and diastolic blood pressure was lower by 20.4 torr and 10.5 torr, respectively. 3) 10 minutes after intravenous administration of 1.0mg propranolol during halothane anesthesia, the heart rate was decreased by 7.8, 7.0 per minute: systolic and diastolic blood pressure decreased by 6.7, 5.7 torr and 3.0, 3.9 torr in the atropine and isoproterenol group, respectively. 4) One minute after intravenous administration of atropine 0.5mg after propranolol 1.0mg during halothane anesthesia, the heart rate increased by 12.1 per minute and persisted so far 10 minutes, but the blood pressure did not increase. 5) One minute after intravenous administration of isoproterenol 0.025mg after propranolol 1.0mg during halothane anesthesia, the heart rate had markedly increased by 35, but normalized 10 minutes later. The systolic blood pressure was increased by 13.4 torr but normalized 10 minutes later. 6) The above results indicate: Atropine increases the heart rate which has been slowed with propranolol during halothane anesthesia: isoproterenol increases the heart rate and blood pressure but the duration of action was short. Therefore, authors considered that atropine is useful for the maintenance of heart rate, and continuous administration of isoproterenol for maintenance of blood pressure and heart rate after propranolol during halothane anesthesia.

5.Studies on Bradycardiac Effect of Methoxamine in Rabbits.
Korean Journal of Anesthesiology 1987;20(3):341-348
The bradycardiac and presor to intravenous and intraventricular methoxamine were examined in urethane-anesthetized rabbits 1) Intravenous methoxamine produced bradycardiac pressor responses. Atropine (2 mg/kg, i,v.) weakened but not abloished the bradycardiac effect. 2) The bradycardiac effect elicited by intravenous methoxamine was not affected by int-ravenous prazosin, rehimbiine, guanethidine and propranolol, butt was attenuated by intra venous chlorisondamine reserpine. 3) The pressor effect elioited by intravenous methoxamine was weakened by prazosin, but was scarcely affected, rather potentiated, by intraTenous yohimblne, guanethidine, chlorisondamine, propranolol and resperpine. 4) Intraventricular methoxamine produced pressor and bradycardiac responses. 5) The bradycardiac effect elicited by intraventricular methoxamine was net affected by intravenous atropine, prasosin and yohimbine. This was attenuated by intravenous guane- thidine, chlorisondamine, propranolol and reserpine, and by intraventricular atropine prazosin and propranolol, respectively. 6) The pressor effect elicited by intraventricular methoxamine was attenuated by intra- ventricular and intravenous prazosin. This was not affected by intravenous atropine, gua-nethidine, chlorisondamine, propranolol, reserpine and yohimbine, and by intraventricular atropine, prasosin and Propranolol, respectivelr. 7) From these results it was inferred that bradycardiac effect elicited by methoxamine was not an action through the mediation of aleph 1-adrenoceptors but was a result from non-specific actions on some brain receptors.

In order to observe the effect on liver function after exposure to enlurane which has relatively minimal hepatotoxic effect, we evaluated the changes of the s-GOT & s-GPT levels caused by general anesthesia with enflurane. This study was undertaken to evaluate the effect of enflurane on liver function by comparing the preoperative and postoperative(1st day, 3rd day, 5th day, and 7th day) liver function(s-GOT & s-GPT) tests is il cases of the first general anesthesia with enflurane and 15 cases of a second general anesthesia with enflurane. The results were as folllows: 1) The 1st operative group. a. There are 5 cases (45%) of significant changes of s-GOT levels and no case of significant change in sGPT levels. b. In most of cases, the level of s-GOT & s-GPT have returned to normal values on the 7th postoperative day. 2) The 2nd operative group. a. The increase in the levels of s-GOT was found in 10 cases, and the s-GPT in 6 cases. b. Postoperatively, the simultaneous increase in the levels of s-GOT & s-GPT were found in 4 cases. c. On the 7th postoperative day, the levels of s-GOT & s-GPT was not normal in 3 cases, and not normal for s-GPT in 2 cases. The above results show that the higher of levels of s-GOT & s-GPT after the second general anesthesia with enflurane apparent compared to the levels after the first general anesthesia with enflurane. And it can be assumed that the extreme precaution is necessary in conduction the second general anesthesia with enflurane.

A xanthoma is a localized collection of tissue histiocytes containing lipid and is usually associated with hyperlipidemia. Tendinous and tuberous xanthomatosis have been found in association with familial hypercholesterolemia, Type III hyperlipidemia, beta-sitosterolemia and cerebrotendinous xanthomatosis. Tendinous and tuberous xanthomatosis without hyperlipidemia have been reported very rarely. Especially tendinous xanthomatosis without hyperlipidemia have not been reported at all in korea. We are reporting a patient with tendinous and tuberous xanthomatosis accompanied by normal plasma lipids

Korean Journal of Head and Neck Oncology 2020;36(1):33-38
Secretory carcinoma of salivary gland origin is a recently described tumor that harbors a characteristic ETV6-NTRK3 translocation that is identical to secretory carcinoma of the breast. The majority of tumors were located in the parotid gland and other major salivary glands, while the minority occurred in a minor salivary gland. We present a case of a 71-year-old female who was diagnosed with low-grade salivary gland cancer presenting in the soft palate accompanying lymph node metastasis. Peroral wide excision, selective neck dissection, reconstruction with radial forearm free flap was performed. The final pathology report indicated secretory carcinoma of the soft palate. The patient was followed-up without evidence of recurrence for one year. At present, it is difficult to accurately assess prognosis and treatment for the secretory carcinoma of the minor salivary gland origin. Continuous follow-up with various cases is needed further.
