A correspondence between quaternionic regular functions in the sense of Fueter and fundamental 2-forms on a 4-dimensional almost Kahler manifold is shown.
We present the result of the theory of quaternionic Fueter regular functions. It is shown that the module of such function ||F(q)||, q := w+ix+jy+kz, cannot be an analytic function in r; r2 := ||q||2 := w2 + x2 + y2 + z2.

Using the fundamental notions of the quaternionic analysis we show that there are no 4-dimensional almost Kahler manifolds which are locally conformally flat with a metric of a special form.
