Laryngoscopy and endotracheal intubation are potent stimuli that increase heart rate and blood pressure. These transient stress responses are probably not harmful in healthy individuals. However hypertensive patients are more prone to have significant increase in heart rate and blood pressure whether they have been treated beforehand or not and these responses also can lead to fstal complications. A randomized double-blind study was csrried out on 40 ASA physical status II-III adult elective surgical patients with hypertension to assess the effects of continuous intravenous infusion of esmolol, ultrashortacting cardioselective beta blocker, on hemodynamic responses to laryngoscopy and endotracheal intubation. Patients received a continuous infusion of esmolol(500mcg/kg/min for 1 minute, followed by 200mcg/kg/min for 12minutes) or an equal volume of saline before and throughout the induction periods of anesthesia. Using noninvasive automatic blood pressure monitor, blood pressure( systolic, diastolic and mean arterial pressure) and heart rate were measured at 6 points: 1) as the control value, on arrival to operating room, 2) just after IV loading dose of saline or esmolol, 3) just after IV thiopental, 4) 1 minute after intuhation, 5) 3 minutes after intubation, and 6) 5 minutes after intubation. The rate-pressure product was calculated in each time. During this study, anesthesia was maintained with enflursne-N2O-O2 vecuronium and controlled ventilstion. In patients given esmolol, systolic pressure, diasolic pressure, mean arterial pressure, heart rate, and rate pressure product at 1 minute, 3 minutes, 5 minutes after intubation were less increased than control group. And the heart rste response was more effectively blunted than the blood pressure response. The continuous infusion of esmolol can blunt hemodynamic changes caused by laryngoscopy and endotracheal intubation in hypertensive patients, yet it is needed to find out the optimal dosage of esmolol for complete blocking of the sympathetic response without the adverse effects.

PURPOSE: Surface antigen 3 (SAG3) of Toxoplasma gondii is very similar in structure to the major surface antigen 1 (SAG1). Although numerous studies have supported the importance of SAG1 in protection against T. gondii infection, few reports exist on SAG3. MATERIALS AND METHODS: Glutathione-S-transferase (GST)-fused SAG3 of T. gondii (rSAG3) were immunized into BALB/c mice alone or in combination with Quil A (rSAG3/Quil A), and then evaluated the protective immunity in vivo and in vitro against murine toxoplasmosis. RESULTS: Immunization with rSAG3 or rSAG3/Quil A resulted in significantly more survival days and fewer brain cysts after challenge with T. gondii compared to an infected control group. Mice immunized with rSAG3 alone or in combination with Quil A produced significantly more specific IgG2a antibody, whereas specific IgG1 antibody titers did not increase. The percentage of CD8+ T cells, IFN-gamma mRNA expression, and nitric oxide production significantly increased in rSAG3- and rSAG3/Quil A-immunized mice. CONCLUSION: These results indicate that vaccination with Toxoplasma rSAG3 results in partial protective immunity against T. gondii infection through induction of a Th1-type immune response, and that protective immunity is accelerated by the modulating effects of Quil A.

Nine adult patients with non-traumatic primary intraventricular hemorrhage (PIVH) were reviewed. Lack of lateralizing sign could be one of the differential points between PIVH and secondary intraventricular hemorrhage (SIVH). In three cases, vascular malformations were identified. Bleeding diathesis was present in one. The pathogenesis of hemorrhage in the remaining five cases was speculated. According to the mainly involved ventricle, prognosis was presumed to be variable. From this study, we conclude that for PIVH investigation including angiography and/or magnetic resonance imaging should be done to identify the etiology and to conduct appropriate management. Survival was more common than SIVH.

This study was performed to investigate the therapeutic effect of electroacupuncture and moxibustion on abomasal displacement in dairy cattle.After acupuncture needles were inserted bilaterally into the acupoints, 'Pi yu', 'Wei yu' and 'Guan yuan yu', electronic stimulation (5 Hz and 10 V, 20 minutes) was conducted once a day for 3 days consecutively. Modified moxa patch was also applied at the same acupoints as in acupuncture for 3 days consecutively.Ten among twelve cows with abomasal displacement were recovered by electroacupuncture and moxibustion, but two were treated with paramedian abomasopexy. It is considered that electroacupuncture and moxibustion may be convenient, safe and economical therapeutic alternatives available instead of surgical procedures on abomasal displacement in dairy cattle.

We studied to investigate the predictive values of gated SPECT for the improvement of wall motion after bypass surgery. As we compared postoperative SPECT with preoperative ones, we defined viability as wall motion improvement. We performed rest 71-201/stress Tc-99m-MIBI gated SPECT in 25 patients before and 3 months after bypass surgery. Myocardial wall motion was graded as normal, hypokinesia, akinesia, and dyskinesia by pair-wise visual analysis of gated pre and postoperative SPECT's on the same monitor screen. Myocardial wall thickening was determined good or poor Among 92 segments with wall motion abnormalities before operation, 69 (75%) improved and 23 did not. Before operation, we could find segments with good systolic thickening in 64 segments among total 92. Thickening of the remaining 28 was poor. Wall motion improved postoperatively in 45 segments (70%) among 64 with good thickening. Twenty four(86%) among 28 segments with poor thickening had also improved. We grouped segments into mild(hypokinetic) and severe(akinetic/dyskinetic) ones. Among 33 segments with severe motion abnormalities, 14 had good thickening and 19 did not. Nine(60%) improved out of 14 segments having severe abnormality with good thickening. However, 16(84%) segments out of 19 having severe abnormality with poor thickening also improved. Neither degree of perfusion decrease nor severity of wall motion abnormalities could explain the high rate of false negatives. In conclusion, as we defined viability as wall motion improvement by comparing pre and postoperative SPECT, systolic thickening observed by gated Tc-99m-MIBI SPECT in myocardial segments with wall motion abnormalities predicted wall motion improvement after bypass surgery. However, poor thickening could not be referred as evidence of nonviable myocardium both in mild and severe contractile dysfunction, so that we might need stimulation study such as dobutamine echocardiography or dobutamine gated SPECT.
