ABSTRACT
Abstract The present study determined some biological compounds, radical scavenging activity and antimicrobial capacity in seeds of Satureja hortensis L. and Mentha spicata L. subsp. spicata. Alpha-linolenic acid (C18:3 n3) has been found to be the major polyunsaturated fatty acid of Satureja hortensis L. (66.24 ± 1.24%) and Mentha spicata L. subsp. spicata (48.17 ± 1.01%). Linoleic acid (C18:2 n6) is identified as the second major polyunsaturated fatty acid in the present study and oleic acid (C18:1 n9) is determined as the major monounsaturated fatty acid. Current study showed that Satureja hortensis L. and Mentha spicata L. subsp. spicata have low levels of saturated fatty acids. It has been demonstrated that ergosterol (263.1 ± 2.14 µg/g), stigmasterol (39.07 ± 0.91 µg/g) and beta-sitosterol (14.64 ± 0.49 µg/g) have been found in Mentha spicata L. subsp. spicata, while ergosterol (69.41 ± 1.75 µg/g) and beta-sitosterol (19.81 ± 1.14 µg/g) have been determined in Satureja hortensis L. Also, this study determined that Satureja hortensis L. and Mentha spicata L. subsp. spicata have low lipide-soluble vitamin content. Furthermore, it has been found that Satureja hortensis L. contains naringenin (612.57 ± 2.57 µg/g), morin (86.97 ± 1.12 µg/g), quercetin (22.87 ± 0.75 µg/g), and kaempferol (20.11 ± 0.94 µg/g) while naringenin (135.91 ± 1.91 µg/g), naringin (61.23 ± 2.15 µg/g) and quercetin (47.51 ± 1.17 µg/g) have been detected as major flavonoids in the seeds of Mentha spicata L. subsp. spicata. The results of the present study suggest that methanol extracts of Satureja hortensis L. and Mentha spicata L. subsp. spicata have significant free radical scavenging activity. The present results revealed that Satureja hortensis L. and Mentha spicata L. subsp. spicata showed major activity against gram-positive and gram-negative microorganisms, fungi and yeast.

O ácido alfa-linolênico (C18: 3 n3) foi o principal ácido graxo poliinsaturado de Satureja hortensis L. (66,24 ± 1,24%) e Mentha spicata L. subsp. spicata (48,17 ± 1,01%). O ácido linoléico (C18: 2 n6) é identificado como o segundo principal ácido graxo poliinsaturado no presente estudo e o ácido oleico (C18: 1 n9) é determinado como o principal ácido graxo monoinsaturado. O estudo atual mostrou que Satureja hortensis L. e Mentha spicata L. subsp. spicata tem baixos níveis de ácidos graxos saturados. Foi demonstrado que ergosterol (263,1 ± 2,14 µg/g), estigmasterol (39,07 ± 0,91 µg/g) e beta-sitosterol (14,64 ± 0,49 µg/g) foram encontrados em Mentha spicata L. subsp. spicata, enquanto o ergosterol (69,41 ± 1,75 µg/g) e beta-sitosterol (19,81 ± 1,14 µg/g) também foram determinados em Satureja hortensis L., este estudo determinou que Satureja hortensis L. e Mentha spicata L. subsp. spicata tem baixo teor de vitaminas lipossolúveis. Além disso, verificou-se que S. hortensis L. contém naringenina (612,57 ± 2,57 µg/g), morina (86,97 ± 1,12 µg/g), quercetina (22,87 ± 0,75 µg/g) e kaempferol (20,11 ± 0,94 µg/g) enquanto a naringenina (135,91 ± 1,91 µg/g), a naringina (61,23 ± 2,15 µg/g) e a quercetina (47,51 ± 1,17 µg/g) foram detectadas como flavonóides importantes nas sementes de Mentha spicata L. subsp. spicata.

ABSTRACT
We report a case that developed acute postoperative endophthalmitis after transconjunctival sutureless vitrectomy using the 23-gauge system. A 66-year-old man underwent non-sutured 23-gauge pars plana vitrectomy for epimacular membrane. Since the patient developed signs of acute endophthalmitis and decreased visual acuity to counting fingers on the second postoperative day, re-vitrectomy with silicone oil was performed. The patient responded well to re-vitrectomy, injection of silicone oil and intravitreal antibiotic injections. Methicillin resistant Staphylococcus epidermidis was cultured from vitreous samples. Silicone oil was extracted at 11 months. The patient remains stable at 14 months with a final visual acuity of 20/50.
ABSTRACT
OBJECTIVE: We aimed to review characteristics of mushrooms and mushroom poisoning and compare clinical picture, laboratory data, treatment modalities and prognostic factors in children with amanita intoxication and non-amanita mushroom poisoning. METHODS: We analyzed 39 pediatric patients through 1994-2004, retrospectively from the patient files and evaluated the patients in two groups as patients with amanita intoxication and patients with non-amanita mushroom poisoning. All of the cases were admitted to the hospital in autumn. Twenty three (59%) of the patients were female and 16 (41%) were male. Mean age of the patients was 8.05 +/- 2.10 years. RESULTS: Amanita phalloides toxin was detected in the serum in 8 patients. Eleven (28%) of the cases were strongly suggestive of amanita poisoning but alpha amanitin level could not be studied. The average time of appearance of symptoms after mushroom consumption, duration of symptoms, hospital stay, serum AST, ALT, PT and creatinine levels were significantly higher in patients with amanita poisoning (p<0.01). Conventional therapy, antidote therapy together with hemoperfusion were carried out in 16 (41%) of the patients. Four of the patients in whose blood amatoxin was detected (50%) and 3 of the patients highly suggestive of amanita poisoning (30%), totally 7 patients died of hepatic coma. The average time of admission to hospital, mean AST, ALT, creatinine and PT values at 3rd day were significantly higher in patients who died of hepatic coma. Prognosis was better in case of early admittance to hospital in patients with amanita poisoning. CONCLUSION: Early diagnosis and treatment in mushroom poisoning can be life saving. Public awareness is very important in prevention of intoxication as well as encouraging early admission to hospitals.

The distribution of creatinine, one of the toxic guanidine compounds, in various tissues has not been studied in detail by using radiolabeled creatinine. Our objective was to investigate the biodistribution of creatinine labeled with 99m technetium (99mTc) by the stannous (II) chloride method in healthy male Wistar rats. Quality controls were carried out by radio thin layer chromatography, high-performance liquid chromatography, and paper electrophoresis. The labeling yield was 85 ± 2 percent under optimum conditions (pH 7 and 100 æg stannous chloride). Rats (N = 12) were injected intravenously with 99mTc-creatinine and their blood and visceral organs were evaluated for 99mTc-creatinine uptake as percent of the injected dose per gram wet weight of each tissue ( percentID/g). The lowest amount of uptake was detected in the brain and testis. When the rate of uptake was evaluated, only the kidney showed increasing rates of uptake of 99mTc-creatinine throughout the study. Kidneys showed the highest amount of uptake throughout the study (P < 0.001 compared to all other organs), followed by liver, spleen and lung tissue.

In patients with Mycoplasma pneumonia extrapulmonary manifestations such as encephalitis, meningitis, cerebellar and brain stem involvement, cranial nerve lesions, peripheral neuropathy, polymyositis have been observed. We report a 16-year-old girl with M. pneumonia infection, acute behavioral changes and coma. Treatment with high dose methyl-prednisolone and clarithromycin led to rapid clinical improvement.
