The human gastrointestinal tract is more complex in its structure and volume of its functions, an organ, or rather, a system of organs. In addition, the intestinal microbiota, which, in turn, is part of the brain-intestine-microbiota axis, is also included in the process of implementing the tasks of the gastrointestinal tract. In this regard, not only instrumental, such as radio-radiological, ultrasound, endoscopic (with subsequent study of biopsy material) and other research methods are relevant, but also laboratory ones aimed at obtaining information about the microbiome and signal molecules involved in regulatory processes gastrointestinal tract. This literature review is devoted to the analysis of modern research methods for neurotransmitters synthesized by the digestive tract and of diagnostic value.

A study of the diagnostic value of tissue eosinophil infiltration in the structure of polyps of the human gastrointestinal tract and surrounding tissues was carried out. We investigated intestinal biopsies from 189 patients aged 40–90 years with polyps, cancer, metastases. This retrospective study allows us to note the possibility of using eosinophils in the development of criteria for early malignancy and a promising outcome of neoplasms in the mucous membrane. Eosinophils are important players in intercellular interactions within the polyp structure and the tissues around it. The complete absence of eosinophils in the tissue of malignant polyps indicates the malignancy of the neoplasm. We revealed relationship between apoptosis and eosinophilic infiltration; both of them affect the outcome and prognosis of polyp development. Apoptosis induction by eosinophils and programmed cambium necrosis in tumor progression need to be further researched.

In the discipline of Islamic law research, strong proofing and clear Istinbat method are key pillars in the construction of Islamic law based on the application of the science of usul al-fiqh and maqasid al-shari'ah. However, what happens at the state of Johor’s fatwa institution is the opposite. The fatwa research methods applied by the Fatwa Committee of Johor in resolving current fatwa issues is not based on the right and true discipline of Islamic law research. In fact, current inputs related to fatwa issues are not explicitly stated in the method of determining the law either in the form of reality or scientifically verified. Therefore, this paper will discuss the fatwa procedures undertaken by the Fatwa Committee of Johor based on the methods applied in resolving current issues. The research methodology adopted is library and interview methods. This study shows that fatwa management and production in the state of Johor is placed under the jurisdiction of the Mufti of Johor’s Department. The methods adopted by the Fatwa Committee of Johor covers two methods, namely: internal research methods including literature review through the application of original source and proofs based on syarak. Second: field research method that includes an external review or going to the location of study such as conducting observation, questionnaires and interviews including referrals to specialists of different fields. Maslahah and mafsdah consideration are also implemented by the Fatwa Committee in every fatwa decision based on the standard that meets the interests of maqasid al-shari'ah. Keywords: Metode, fatwa, istinbat, usul al-fiqh, maqasid al-shari’ah ABSTRAK Dalam disiplin penyelidikan hukum Islam, kekuatan pendalilan dan kaedah istinbat yang jelas merupakan tunggak utama dalam pembinaan hukum Islam berasaskan kepada aplikasi ilmu usul al-fiqh dan maqasid al-shari’ah. Namun begitu, apa yang berlaku di institusi fatwa negeri Johor adalah sebaliknya. Kaedah penyelidikan fatwa yang diaplikasi oleh Jawatankuasa Fatwa Negeri Johor dalam menyelesaikan isu fatwa semasa tidak berasaskan kepada disiplin penyelidikan hukum Islam yang tepat dan sebenar. Malahan input-input semasa yang berkaitan dengan isu fatwa juga tidak dinyatakan secara jelas dalam kaedah penentuan hukum sama ada dalam bentuk realiti yang berlaku atau pembuktian secara saintifik. Justeru, kertas kerja ini akan membincangkan prosedur fatwa Jawatankuasa Fatwa Negeri Johor berdasarkan metode-metode yang diaplikasi dalam menyelesaikan isu-isu yang bersifat semasa. Metodologi kajian yang digunakan dalam kajian ini adalah melalui metode perpustakaan dan metode lapangan. Hasil kajian menunjukkan bahawa pengurusan dan pengeluaran fatwa di negeri Johor hanya terletak di bawah bidang kuasa Jabatan Mufti Johor. Metode fatwa yang diamalkan oleh Jawatankuasa Fatwa Negeri Johor merangkumi dua metode iaitu pertama, kaedah penyelidikan dalaman yang merangkumi kajian kepustakaan menerusi pengaplikasian dari sumber asas dan dalil-dalil syarak. Kedua, kaedah penyelidikan lapangan yang meliputi kajian luaran atau turun ke lokasi kajian seperti observasi, soal selidik dan temubual dan rujukan kepada pakar dalam bidang yang berlainan. Pertimbangan maslahah dan mafsdah juga dimplementasikan oleh Jawatankuasa Fatwa dalam setiap keputusan fatwanya berasaskan standard yang menepati kepentingan maqasid al-shari’ah. Kata kunci: Metode, fatwa, istinbat, usul al-fiqh, maqasid al-shari’ah
