The rapid increase in the global production of apples has led to improved monitoring and control of toxic substances present in apples and their derivatives. One of these toxic substances is patulin, a mycotoxin and secondary metabolite produced by different fungi species of the genera <em>Penicillium, Aspergillus, Gymnoascus, Paecilomyces</em> and <em>Byssochlamys.</em> This study evaluated patulin levels in juice produced from Fuji apples subjected to different temperature conditions and storage times in southern Brazil. The apples were divided into groups weighing 1 kg and stored at the following temperatures: 0ºC, 5ºC, 6.7ºC, 19.5ºC and 25ºC. Sub-samples of each group were processed to determine their patulin level by HPLC at the following intervals: 0 (control group), 7, 14 and 21 days. After 28 days of storage at all temperatures, the apples could not be analyzed due to their deterioration. The results indicated that at all temperatures; there was variation in the patulin levels. The smallest patulin value was observed in apple juice stored at 19.5°C and 25°C.

Tanggal Submit:28 Januari 2019 Tanggal Review:30 April 2019 Tanggal Publish Online:17 Mei 2019 Potatoes are one of the vegetables that contain substances that are important for the formation of body tissues, such as protein and fat. Potatoes also form red blood cells or hemoglobin (Ca, P and Fe). In Indonesia tend to process potatoes using only meat. The skin is removed, even though the nutritional content of the skin is five times greater than the meat. Potato peels that supply querestin, antioxidants and flavonoids that act as free radical acceptors. (Free radicals are reactive molecules that cause damage to the body that can lead to diseases such as heart disease and cancer) in the skin of potatoes found also effective antioxidants, chlorogenic acid. Potato skin is also proven to increase hemoglobin levels (Khomsan, A, 2009). However, that does not mean potato skin does not have adverse side effects, if the use is not appropriate. In order to use it optimally, you need to know enough information about the advantages and disadvantages and the possibility of abuse. However, the level of toxicity from potato skin is still unknown. Brine Shrimp Lethality Test (BSLT) is one of the oxicity test methods that is widely used in tracing bioactive compounds that are toxic from natural materials. This research is an experimental research with post test-only control group design approach. Treatment with giving potato skin juice to Artemia salina Leach larvae with the aim to determine the potential of plant biological activity based on the toxicity of secondary metabolites contained in it, and at the same time as the initial screening test of anticancer activity of chemical compounds in potato skin juice. The results showed the LC50 value was at a concentration of 0.5% to 1% and based on the results of SPSS 21 analysis with probit analysis obtained LC50 price data of 0.746 gr / ml (7460 μgr / ml), based on the results of research and data analysis it can be concluded that potato skin has an LC50 value at a concentration of 0.746 gr / ml (7460 µgr / ml). With an LC50 price of more than 1000 µg / ml according to the BST method the potato skin does not have the potential for toxicity so the skin of the potato has the potential as an alternative to increasing hemoglobin levels.Keywords: potato skin, toxicity, BSlT

The present work aimed to evaluate in vitro the molluscicidal activity and latex toxicity of Euphorbia milii var. splendens (Bojer ex Hook) Ursch & Leandri for the control of mollusks of the species Biomphalaria tenagophila. Specimens of E. milii var. splendens cultivated in the rural region of Pindamonhangaba were selected, from which latex was obtained by the transverse incision of the aerial parts. For the molluscicide test, adult mollusks of the species B. tenagophila were separated into groups of 10 and submitted to latex immersion at concentrations of 2.5 ppm, 1.25 ppm, 0.625 ppm, and 0.3125 ppm for 24 hours. In parallel, the toxicity of latex at a concentration of 0.3125 ppm was determined by testing with Artemia salina (mortality assessment) and using the Allium cepa test (determination of growth inhibition, amount, and weight of roots). It was observed an important molluscicidal activity of E. milii var. splendens latex at the various concentrations evaluated. In addition, it was also possible to observe moderate toxicity against A. salina nauplii and in the toxicity test with A. cepa. This demonstrates the potential of using latex from E. milii var. splendens to control populations of B. tenagophila species, not only for the observed molluscicidal activity but also for the moderate mortality of A. salina nauplii, whereas in the A. cepa test no change was observed in the parameters evaluated in relation to the control group, demonstrating safety for use in the environment.

ABSTRACT The fractional determination of 17-ketosteroids in the daily urine was performed in nine cases of hyperemesis gravidarum and in four control cases, in the first trimester of pregnancy both before and after corticotrophin administration. The excretion of total 17-KS is similar in the two groups. Only in the hyperemesis group does the excretion of total 17-KS increase significantly after corticotrophin administration. The fractional determination reveals no difference between the two groups of patients with regard to the values of the fractions U (unidentified 17-KS), A (androsterone) and Rest (11-oxygenated 17-KS). The excretion of dehydroepiandrosterone is significantly higher in the hyperemesis group than in the control group. The excretion of androstanolone seems to be lower in the hyperemesis group than in the control group, but the difference is not statistically significant. The differences in the correlation between dehydroepiandrosterone and androstanolone in the two groups is significant. The high excretion of dehydroepiandrosterone and low excretion of androstanolone in cases of hyperemesis gravidarum is a sign of adrenal dysfunction.

Aim. To study the influence of deproteinized dialysate from blood of milk-fed calves on the type of exudative discharge and dynamics of inflammatory reaction after hernia repair with plastics of the anterior abdominal wall with hernioendoprosthesis of polypropylene. Materials and Methods. The study involved 59 patients being on stationary treatment in the surgical department of Kursk Regional Clinical Hospital. Patients were hospitalized for the herniation of small or medium dimension. The patients were divided to two groups: the main (n=30) and control (n=29) groups. After endoprosthetics, the patients of the control group were given complex conservative treatment. The patients of the main group, besides standard treatment, were administered deproteinized dialysate from blood of milk-fed calves intravenously in drips 10 ml + 200 ml of 0.9% sodium chloride solution within 7 days. For cytological examination and determination of the type of cytograms, the traumatic discharge was collected and analyzed using the method of M.F. Kamaev and M.A. Palthsev. Results. Cytomorphometric examination was conducted on the third, fifth and seventh day after endoprosthetics with the aim of studying dynamic changes. Determination of cell composition and also of its changes characteristic of each studied period, was necessary for obtaining further information characterizing inflammatory process in the region of placement of the endoprosthesis. After endoprosthetics in patients who were administered hemodialysate, the inflammatory reaction was less pronounced than in patients who did not receive the preparation. This was associated with a more dynamic change of stages of the inflammatory process. In patients of the main group who received deproteinized dialysate, regenerative type of inflammation first appeared on the fifth day and made 6.9%; by the seventh day the share of patients with the regenerative type rose to 17.5%, while in the patients of the control group no regeneration stage was observed in both periods. Conclusion. Analysis of the efficiency of influence of hemodialysate on the inflammatory reaction in plastics of the anterior abdominal wall with polypropylene endoprosthesis evidences faster course of all stages of inflammation and reduction of its intensity by 10%.

Abstract This study describes changes in haematological parameters, cytokine profile, histopathology and cortisol levels in Swiss mice experimentally infected with Angiostrongylus costaricensis. Twenty-eight Swiss mice were divided into two groups (G1 and G2) of 14 animals each. In each group, eight animals were infected orally with ten third-stage larvae of A. costaricensis and six were used as a control group. The mice of groups G1 and G2 were sacrificed 14 and 24 days after infection, respectively. Samples were collected for histopathological and haematological analyses and determination of the cytokine profile and cortisol levels. Granulomatous reaction, eosinophilic infiltrate and vasculitis in the intestinal tract, pancreas, liver and spleen were observed with varying intensity in infected animals. Our results showed that the mice developed normocytic and hypochromic anaemia, and that the histopathological lesions caused by the experimental infection influenced increases in cortisol, neutrophil and monocyte levels. In addition to this, we detected increased interleukin-6 and tumour necrosis factor alpha levels in the infected animals.

AbstractCompanion animals, including bitches, may be exposed to zearalenone (ZEN) toxins that are often present in feed, and ZEN intoxication may lead to ovarian dysfunction. This study involved evaluation of the degree of ZEN-induced hypo stimulation of ovary by determination of proliferative and apoptotic indices and description of the ultra-structural organization of ovarian follicles in pre-pubertal bitches subjected to experimental, long-term exposure to low-dose ZEN mycotoxicosis. The experiment involved 30 clinically healthy, immature Beagle bitches aged approximately 70 days with initial average body weight of 8 kg, randomly divided into three groups of 10 animals each: two experimental groups (EI and EII) and a control group (C). Over a period of 42 days, ZEN was administered per os to EI animals at a dose of 50 μg/kg BW, and to EII bitches at a dose of 75 μg/kg BW. Control group animals were fed placebo containing no ZEN for 42 days. Analytical samples of the mycotoxin were administered daily in gelatin capsules before morning feeding. All the bitches were subjected to ovario-hysterectomy at the end of the experiment. Proliferation index (PCNA method) and apoptotic index (TUNEL test) values were determined by immune-histological analyses. The median for apoptotic index was determined at 13.45 for group EI, 17.84 for group EII, and 8.59 for group C. The median for proliferation index was determined at 35.25 for group EII, 42.44 for group EI, and 70.60 for group C. The results of ultra-structural examinations of the ovaries revealed that experimental, ZEN-induced hyperestrogenism enhanced apoptosis and lowered the proliferative ability of follicular cells what contributed to organelle destruction in pre-pubertal bitches. The changes observed were particularly advanced in EII animals, which were administered a higher dose of ZEN.
