There have been multiple reports already regarding acute carbon monoxide/CO poisoning in the Philippines secondary to misuse of portable generators, especially during the times of typhoon. We present a case of unintentional carbon monoxide poisoning in a Filipino household wherein three of its members were found dead and leaving other five unconscious before they were rushed to the hospital. The index patient had increased serum fraction percentage of carboxyhemoglobin level and presented with rhabdomyolysis during admission. Neuroimaging confirmed a hypoxic-ischemic encephalopathy secondary to carbon monoxide intoxication. Even without hyperbaric oxygen therapy, patient improved with adequate hydration, early rehabilitation and trauma-focused psychotherapy.

Carbon monoxide which is an odorless, colorless, non-irritating gas causes asphyxia by blocking the hemoglobin of the RBC from carrying oxygen to the tissues and from returning carbon dioxide to the lungs. The clinical symptoms of CO poisoning depend on the blood CO saturation level and in a healthy middle-aged individual a blood CO saturation greater than 50% is considered fatal. In forensic science, the investigation of the scene in cases of CO poisoning is imperative to determine the manner of death or the source of CO production, while postmortem diagnosis of CO poisoning is not difficult. The author reported four cases of CO poisoning in the unusual or atypical circumstances, which were not recognized in the scene.

Effect of acute carbon monoxide poisoning on prostatic acid phosphatase in white rat hag been studied histochemically. The experimental animals were exposed to 0.25% and O. 5% of carbon monoxide from 5 minutes to 4 hours duration. Gomori's modified method was used for acid phosphatase test. Following results are obtained: 1. The acid phosphatase activity increases after 30minutes of exposure in both experimental groups, 0.25% and 0.5% of carbon monoxide, and the changes of acid phosphatase activity become more significant according to the duration of exposure. 2. The changes of acid phosphatase activity are similar in both experimental groups exposed to 0.25% and 0.5% of carbon monoxide. 3. No significant histopathological changes are observed in rat prostate gland.

PURPOSE: Electrocardiographic findings such as Tp-Te interval, Tp-Te dispersion, and Tp-Te/QT ratio could be used to predict dysrhythmic events regarding any kind of toxic materials. We investigated the prevalence of cardiac toxicity related to acute carbon monoxide (CO) poisoning and the characteristics of electrocardiographic changes corresponding to the severity of intoxication. METHODS: This retrospective observational study was conducted with 113 patients of acute CO poisoning from May, 2013 to July, 2014. Myocardial injury (MI) was determined based on an elevation of serum troponin T within the first 24 hours of the ED visit. The study population was classified according to Acute Neuropsychiatric Status (ANS) scoring: a mild intoxication group (ANS scores 0 and 1) and a severe intoxication group (ANS scores 2 and 3). RESULTS: Prevalence of MI was higher in the severe intoxication group of acute CO poisoning (p<0.001). QTc was significantly prolonged in the MI group (p=0.007). However, no differences in other electrocardiographic parameters were observed between MI group and non-MI group. CONCLUSION: Myocardial injury was combined more frequently with a severe intoxication group of acute CO poisoning compared to a mild intoxication group. A specific feature of eletrocardiogram in myocardial injury with acute CO poisoning was a QTc prolongation.

Pathophysiology of acute carbon monoxide poisoning is not clear. It is generally accepted that hypoxic and/or anoxic insult is very significant role in the pathophysiology of acute acrbon monoxide poisoning, but many arguments are documented especially focal hypoxia or metabalic acidosis within brain parenchyme. In sofar such a focal change seems to be largely depend upon focal change of neuroendocrine substances including B-endorphin. Also B-endorphin is known to be responsble to the pathogenesis of cerebral ischemia. Though the possible relationship between the alteration of level of B-endorphin and hypoxia, it is seldom to pay attention to the role of B-endorphin in carbon monoxide intoxication. We measured plasma B-endorphin in acute carbon monoxide intoxication and compared with the value of control group. There was no difference between control group and acute carbon monoxide poisoning group, the possible role of B-endorphin in acute carbon monoxide poisoning should not be excluded. We suggest the more comprehensive and newly programmed study seems to need for clarifying the possible role of B-endorphin in acute carbon monoxide poisoning.

Influence of acute and chronic carbon monoxide poisoning on the rat prostate has been studied enzymologically and the following results were obtained: 1. An increasing tendency of the total lactate dehydrogenase activity in the prostate tissue was observed is the chronic poisoning groups. 2. The lactate dehydrogenase isoenzyme distribution pattern was not remarkably influenced by chronic poisoning. 3. The lactate dehydrogenase isoenzyme distribution pattern is the prostate tissue was as LDH5> LDH4> LDH3> LDH2> LDH1.

Influence of acute and chronic carbon monoxide poisoning on the rat testis has been studied enzymologically and the following results were obtained: Experimental animals were divided as 1) control, C1 (6 animals) 2) acute poisoning with 0.5% carbon monoxide until death, C2 (10 animals) 3) chronic poisoning with 0.05% carbon monoxide for 2 hours daily E1 (5 animals)...3 days/week for 8 weeks E2 (6 animals)...3 days/week for 4 weeks 4) acute poisoning until death with 0.5% carbon monoxide after chronic poisoning with 0.05% carbon monoxide E3 (5 animals)...chronic poisoning for 8 weeks plus acute poisoning E4 (5 animals)...chronic poisoning for 4 weeks plus acute poisoningUsing Neiland's method, the total activities and distribution patterns of lactic dehydrogenase in rat testis were measured. All of the data were analyzed statistically. 1. The total activities of lactic acid dehydrogenase in all experimental groups seemed to increase. In the group E3, the increase was statistically significant.(p<0.05) 2. No significant changes were observed in the lactic acid dehydrogenase isoenzyme distribution pattern of the testis. both is the control and experimental groups. 3. The lactic acid dehydrogenase distribution patterns were as fraction l>2>4>3>5 4. No significant histopathological changes were observed in the rat testis.
