Abstract

Pengaruh globalisasi yang melanda Indonesia menuntut perguruantinggi untuk menghasilkan lulusan yang dapat bersaing dalam duniaglobal. Dokter dituntut setidaknya memiliki kompetensi rata-ratadokter, sebagai wujud prestasi belajar, yang sekualifikasi pada situasidan kondisi yang sebanding dalam melaksanakan prakteknya.Kedisiplinan dan persepsi merupakan beberapa faktor yang dapatmempengaruhi prestasi belajar. Penelitian ini bertujuan untukmengetahui dan menganalisis hubungan kedisiplinan dan persepsimahasiswa tentang PBL dengan prestasi belajar mahasiswa FakultasKedokteran di Universitas Muhammadiyah Surakarta. Jenis penelitianini adalah penelitian kuantitatif observasional analitik (non-experiment)yang menjelaskan hubungan dua variabel, yaitu variabel bebas(kedisiplinan dan persepsi mahasiswa tentang PBL) dan variabel terikat(prestasi belajar). Penelitian ini menggunakan pendekatan crosssectional. Jumlah mahasiswa sebagai sampel sebanyak 56 orang. Datadiperoleh melalui kuesioner, ceklist dan dokumentasi, selanjutnya datadatayang terkumpul diolah dengan menggunakan analisis bivariat.Hasil penelitian menunjukkan bahwa nilai p hasil uji analisis antarakedisiplinan dan indek prestasi adalah 0,312 dan antara persepsitentang PBL dan indek prestasi adalah 0,467, keduanya lebih besar dari0,05. Koefisien korelasi yang ditunjukkan oleh nilai r sangat lemahwalaupun arah korelasi positif. Nilai r hasil uji analisis antarakedisiplinan dan indek prestasi adalah 0,138 dan nilai r antara persepsitentang PBL dan indek prestasi adalah 0,099. Berdasarkan hasilpenelitian dapat disimpulkan bahwa baik variabel kedisiplinan maupunpersepsi tentang PBL, masing-masing tidak menunjukkan hubunganyang signifikan terhadap prestasi belajar. Dengan demikian juga dapatdisimpulkan bahwa terdapat korelasi yang sangat lemah antarakedisiplinan dan prestasi belajar, demikian juga antara persepsi tentangPBL dan prestasi belajar.

Abstract

The mechanisms by which probiotic bacteria affect the immune system are unknown yet, but many of them are attributed to an increase in the innate or in the acquired immune response. The aim of this study was to examine the effect of the probiotic on the histology structure of intestinal layer in a mice model of allergy. Male Balb/C mice were sensitized and challenged intra peritoneally (i.p) with ovalbumin(OVA). Mice were immunized i.p. on days 0 and 7 with 2.5 mg of OVA adsorbed to 7.75ml of Aluminum hydroxide gel. OVA challenges (10 mg in l0 ml of PBS) were administered orally on days 8, 9, 10, 11, 12 and 13, with mice being sacrificed on day 14. This probiotic was orally administered to Balb/C mice. Intestinal microscopic slides were prepared using parafin method and stained with hematoxylin eosin staining. The data were analyzed by Kruskal-Wallis, followed by MannWhitney Test. The results showed that probiotic can minimized inflammation of intestinal layer in the experimental animal, not significantly different with 3rd generation of antihistamine.

Abstract

It was reported in previous studies that pharmacological activities were identified in various compounds extracted from Phyllanthus Acidus (PA) such as anti-inflammatory, antilipoxigenase, anti-allergic and cyclooxigenase inhibitor. It is also acknowledged that Ig E serum level is normally low and usually increase in allergic conditions. This study was aimed to determine the effect of PA leaf extract on Ig E level in mice model of allergic asthma. Male Balb/C mice were sensitized and challenged intraperitoneally (i.p) with ovalbumin(OVA). Mice were immunized i.p. on days 4 and 20 with 2.5 mg of OVA adsorbed to 7.75ml of Aluminum hydroxide gel. OVA challenges (10 mg in l0 ml of PBS) were administered aerosolly on days 26, 29, 32, 39 and 46, with mice being sacrificed on day 47. Ig E level in serum was determined using ELISA kits (Alpha Diagnostic, USA) according to the manufacturer's instructions. A one-way analysis of variance (ANOVA) with LSD post hoc analysis was used to determine significant differences. Results were expressed as mean + SEM, and values of p < 0.05 were considered statistically significant. The results showed that Ig E level in the negative control group was 50.13+33.40 ng/ml, PA leaf extract was 51.17+26.15 ng/ml, and positive control group was 48.97+33.50 ng/ml while OVA group was 152.89+58.00 ng/ml (p >0.05). It was concluded that PA leaf extract could minimize Ig E level, not significantly different with 3rd generation of antihistamine.
