ABSTRAK Cara membatik di Indonesia mulai banyak beralih dari pemakaian bahan alami menjadi bahan cat sintesis. Cat sintetis yang digunakan sering kali mengandung logam berat di antaranya timbal (Pb) dan kromium (Cr). Pemakaian logam berat dalam waktu lama akan mengganggu kesehatan. Penelitian ini dilakukan untuk melihat hubungan kadar logam Pb dan Cr dalam darah dan limbah dengan kadar hemoglobin (Hb) dan Packed Cell Volume (PCV) serta mengetahui prevalensi gejala toksisitas yang dirasakan pada pekerja di tiga sentra batik di Desa Lendah Kulon Progo. Sebanyak 76 pegawai di sentra batik: 37 orang di sentra SB, 20 orang di FA dan 19 orang di SA ditentukan kadar Hb, PCV, kadar Pb dan Cr dengan metode Inductively coupled plasma (ICP). Air limbah lingkungan dari ketiga lokasi sentra batik diambil dan diperiksa kadar Pb dan Cr-nya. Hasil antara ketiga lokasi diuji normalitasnya dan dianalisis dengan analisis varian atau Kruskal-Wallis. Hubungan antara kadar Pb dan Cr baik darah maupun limbah dengan kadar logam berat dalam darah dianalisis dengan uji korelasi Pearson atau Spearman. Hasil dinyatakan berbeda bermakna jika p<0,05. Gejala penyakit yang dialami pekerja yang diperkirakan berhubungan dengan toksisitas logam berat dihitung frekuensinya. Antropometik, tekanan darah, kadar Hb, PCV dan logam berat dari ketiga lokasi yang diperiksa tidak berbeda bermakna (p>0,05). Kadar Pb darah dan krom di sentra SB dan FA berbeda signifikan dengan di sentra SA (p<0,05). Tidak terdapat korelasi yang signifikan secara statistik antara kadar Pb darah, Cr darah, dan Pb limbah dengan kadar Hb dan PCV. Gejala iritasi kulit, pusing, dan nyeri sendi dirasakan 37-49% repsonden. Kadar timbal dan krom darah pembatik di sentra SB dan FA lebih tinggi dari sentra SA. Tidak terdapat hubungan bermakna antara toksisitas Pb dan Cr dengan kadar Hb dan PCV. Gejala toksisitas di antara pekerja batik diperkirakan dapat terjadi karena toksisitas logam berat kronis akibat pemakaian cat batik.KATA KUNCI batik; hemoglobin; chromium; sel darah; timbal ABSTRACT The dye used to color batik has changed from natural to synthetic materials in several places in Indonesia. Synthetic paints often contain heavy metals including lead (Pb) and chromium (Cr). Chronic use of heavy metals can affect health. This study was conducted to examine the relationship between blood and waste water levels of Pb and Cr with hemoglobin (Hb) and Packed Cell Volume (PCV), and to determine how many workers felt the toxicity symptoms in three batik centers in Lendah Kulon Progo. A total of 76 batik center employees: 37, 20, and 19 people from the SB, FA, and SA centers were recruited. Determination of Hb, PCV, Pb and Cr levels were conducted with the Inductively coupled plasma (ICP) method. Wastewater from the three batik centers is taken and examined. The data were analyzed by One-way ANOVA or Kruskal-Wallis. Correlation anayses were performed with Pearson or Spearman correlation test. Results were considered significant if p<0.05. Disease symptoms experienced by workers that are estimated to be associated with heavy metal toxicity are calculated in frequency. Anthropometrics, blood pressure, Hb levels, PCV and heavy metals were not significantly different between centers (p>0.05). Blood Pb and Cr from the SB and FA were significantly different from those at the SA center (p<0.05). There were no statistically significant correlations between blood Pb levels, blood Cr, and Pb waste with hemoglobin and PCV levels. Symptoms of skin irritation, dizziness, and joint pain were felt by 37-49% of respondents. Blood levels of lead and chrome in the SB and FA centers are higher than the SA centers. There was no significant correlation between Pb and Cr toxicity with hemoglobin and PCV levels. Symptoms of toxicity among batik workers are thought to occur due to chronic heavy metal toxicity due to the use of synthetic paint.KEYWORDS batik; haemoglobin; chromium; blood cell; plumbum

Background and aim: High fat and fructose diet may impair β cell function through oxidative stress that is induced by subsequent hypercholesterolemia. The β cell function is usually quantified by homeostatic model assessment beta-cell function (HOMA-β). Oxidative stress may be decreased by β-carotene from pumpkin (Cucurbita maxima). This study aimed to evaluate the effects of pumpkin powder on glucagon-like peptide-1 (GLP-1) level and HOMA-β in rats with high fat and fructose diet.Material and method: A total 25 rats were administered a high fat and fructose diet during 25 days. They were divided into five groups 1) normal, 2) hypercholesterolemic rats 3) hypercholesterolemic rats with 0.16 g pumpkin/200g bodyweight (BW); 4) hypercholesterolemic rats with 0.32 g pumpkin/200 g BW, and 5) hypercholesterolemic rats with 0.64 g of pumpkin/200 g BW. The lipid levels were measured before and after administration of pumpkin for 4 weeks, and at the end of the study, GLP-1 level and HOMA-β were analyzed.Results: Administration of pumpkin to the rats on a high fat and fructose diet reduced total cholesterol, triglyceride, and increased HDL levels. Changes were positively correlated with the amount of pumpkin intake. The decrease of cholesterol levels was positively associated with GLP-1 level, and negatively correlated with HOMA-βConclusions: This study suggested that pumpkin can improve the HOMA-β and decrease GLP-1 levels, possibly by reducing cholesterol levels.

BACKGROUND: High sterol regulatory binding protein 1c (SREBP-1c) gene expression increases triglyceride synthesis, which induces insulin resistance. Short-chain fatty acids (SCFAs) from fiber fermentation and beta carotene may inhibit SREBP-1c gene expression. AIM: The aim of this study was to evaluate the high fiber and beta carotene diet on improving insulin resistance in hypertriglyceridemia rats. METHODS: A total of 25 Wistar male rats were divided into five groups: (1) Normal control (NC); (2) hypertriglyceridemia control (HC); (3) hypertriglyceridemia rats with treatment 1 (HT1); (4) hypertriglyceridemia rats with treatment 2 (HT2); and (5) hypertriglyceridemia rats with treatment 1 (HT3). The HT1, HT2, and HT3 received fiber 1.0 g; 2.0 g; and 3.1 g and beta carotene 725.7 μg; 1451.5 μg; and 2177.2 μg per day, respectively, for 6 weeks. The HC received high fat and fructose diet and the NC received a standard diet. The levels of triglyceride were analyzed using the colorimetric method before and after treatment. At the end of the study, the expression of SREBP-1c was identified by a quantitative polymerase chain reaction. RESULTS: High fat and fructose diet increased the levels of triglyceride (36.53 ± 1.27 vs. 119.79 ± 7.73), but high fiber and beta carotene diet can reduce triglyceride levels in HT1 (94.58 ± 4.53 vs. 77.70 ± 7.97); HT2 (115.58 ± 4.76 vs. 66.90 ± 3.11); and HT3 (103.87 ± 7.47 vs. 62.06 ± 4.45). The decreased triglyceride levels were related to low SREBP-1c gene expression, especially in the liver. Low SREBP-1c gene expression was correlated with homeostatic model assessment of insulin resistance index with r = 0.414; p < 0.05 in the liver and r = 0.158; p > 0.05 in white adipose tissues. CONCLUSION: High fiber and beta carotene diet can improve insulin resistance through inhibition of SREBP-1c gene expression.
