Abstract
One of the disturbing complications of propofol is pain on injection and the incidence ranges from 28% to 90%. Metoclopromide is commonly used as an anti emetic drug. Some investigators reported that this drug could reduce the pain on injection of propofol. The aim of this study was to assess and comparison of the efficacy of propofol pretreatment with metoclopromide in incidence and severity of its pain on injection.
Materials and Methods: In a randomized, prospective, double-blinded, placebo-controlled trail, 150 patients 18 to 40 yr old were randomly allocated in one three groups. C group (2ml of normal saline), L group (40mg lidocaine in 2ml), M group (l0mg metoclopromide in 2ml). Immediately after injection of study or placebo drugs, 10 mg of propofol with injection rate of 0.5 ml/s (In 4 Seconds) were injected in to the same vein that was inserted to the most prominent dorsal hand vein. Pain severity was measured using Visual Analogue Pain Scale that were educated to the patients before the trail (0 for no pain and 100 for the most aggressive pain in life) and values other than zero was encountered pain appearance. Patients with signs of sedation were excluded.
Results: There was no statistically significant difference between patients in three groups in number of men and women (P = 0.66), age (P = 0.29) and weight (P = 0.49). Furthermore severity (P = differences (C = 41.18, L - 25.4 and M = 13.1, P < 0.001) and patients in metoclopromide group experiences lower pain than other two groups (P < 0.001). Pain incidence in Control group was 77.1% and it was significantly reduced in lidocaine and metoclopromide group (P = 0.002), but there were no significant difference between them (P = 0.051). The 0.69) and incidence (P ~ 0.29) of pain has no significant difference between men and women. Pain severity between three groups has significant results showed that metoclopromide could significantly reduce the seventy of pain on injection of propofol more than lidocaine (opposite to diazepam), but they had no difference in pain incidence. It might lie on the different mechanisms that they produce pain. Pain on injection of diazepam is primarily attributed to propylene glycol, as a vehicle, but the pain mechanism in propofol is remaining unknown.
Conclusion: Finally as regards to other useful effects of metoclopromide including postoperative nausea and vomiting and propofol induction dose reduction, especially when there is a medical condition where lidocaine is contraindicated, it may be a reasonable alternative before injection of propofol.

Abstract
Background: The combined MMCOA deficiency and Hemocystinuria results from defect in cb1c & cb1d & cb1F genome. Until now only 100 cases of this disease has been reported. Most of them with cb1c deficiency. Due to this enzymatic defect, mild to moderate retention of Hemocystin (MMA) and their precursors in the body fluids (blood and urine) ensues. Although, acidemia, Hypoglycemia & megaloblastic anemia are common but hyperamonemia and hyperglycemia were not reported in these patients. Our case is a 3 years old girl with known MMCOA deficiency and Hemocystinuria who needed G.A for partial resection of the mandible because of osteomilitis.
Materials and Methods: In this report we explain the preoperative preparation of the patient, induction and maintenance of Anesthesia, and discuss the biochemical, lab results during & after surgery.
Results & Conclusion: Due to our result, the urine and blood hemocystin & MMCOA were not increased. This case is interesting because no theoretical or practical report on the G.A of these patients exists.

Abstract
Background: Both hypoxia and hypocapnia can cause broncho-constriction in humans, and this could have a bearing on performance at high altitude. The objective of this study was to examine how pulmonary ventilatory function during high-altitude trekking.
Methods: This study was a before and after study on spirometric parameters at Base line (1150 m above sea level), and after ascending at 4150 m above sea level. This study was performed in summer 2004 at Cialan Mountain in Iran. Fifty six healthy male University student volunteers were enrolled in the study. Respiratory function was assessed in participants before ascending at baseline (1150 meter) and after ascending at 4150 meter in Cialan Mount with a Spirolab II. Spirometric parameters changes were compared using paired t-test statistical analysis computations were performed by spss 11.5 and p≤0.05 was considered significant.
Results: The mean age and body mass lindex of our subjects were 22.9±5.3 years and 21.5±2.5, respectively. Forced vital capacity (FVC) was significantly decreased with increasing altitude from baseline level (P<0.01). Forced expiratory volume in 1 second to forced vital capacity ratio (FEV1/FVC) and maximal midexpiratory flow rate (FEF 25-75%) were significantly increased with increasing altitude (P=0.001). There was no significant change in forced expiratory volume in 1 second and peak flow (P>0.05). FVC fell by the average of 7.1% at 4150m (2.4% per 1000m increased altitude) in comparison to 1150m.
Conclusion: The changes in some pulmonary ventilatory parameters were proportional to the magnitude of change in altitude during a high-altitude trek.
