<p class="Default"><strong> ABSTRAK</strong></p><p class="Default"><strong>Pendahuluan:</strong> Prevalensi dan keparahan penyakit alergi terus meningkat secara global, terutama di negara dengan pendapatan rendah sampai menengah. Terapi alergi saat ini seperti kortikosteroid banyak memberikan efek samping dalam penggunaan jangka panjang. Ekstrak daun jambu biji (Psidium guajava) berpotensi sebagai antihistamin yang dapat menjadi terapi alternatif penyakit alergi. Penelitian ini bertujuan untuk mengetahui efek antihistamin ekstrak daun jambu biji (Psidium guajava) pada tikus putih (Rattus novergicus) yang diinduksi ovalbumin dinilai dari jumlah eosinofil jaringan kulit. </p><p class="Default"><strong>Metode: </strong>Penelitian ini merupakan penelitian <em>quasi experimental design</em> dengan rancangan <em>post test only with control group design. </em>Subjek penelitian tikus putih jantan<em>, </em>umur 3-4 bulan, dan berat badan 200-300 gram.

Current allergic therapies such as corticosteroids have many side effects in long-term use. Guava leaf extract (Psidium guajava) has the potential as an antihistamine which can be an alternative therapy for allergic diseases. This study aims to determine the effect of antihistamine extract of guava leaves (Psidium guajava) on white rats (Rattus novergicus) induced by ovalbumin assessed from the number of eosinophils of skin tissue.</em><em></em></p><p class="Default"><em> </em></p><p class="Default"><strong><em>Methods</em></strong><em>: </em><em>This research was a quasi experimental design with a post test only design with control group design. The research subjects were male white rats, aged 3-4 months, and weighing 200-300 grams. Samples of 24 white rats were randomly divided into six groups. Normal (K) control group without treatment, negative control (KN) was only induced by ovalbumin, positive control (KP) was given methylprednisolone, and treatment groups (KP1, KP2, KP3) were given guava leaf extract with the following dosage 27 mg / 200 gram BW, 54 mg / 200 gram BW, and 108 mg / 200 gram BW. The effect of antihistamines was assessed through histopathology of skin tissue in the form of an average number of eosinophil infiltrations using a light microscope.
